NI SPEEDY-33 Overview  
Operate the module only at or below Pollution Degree 2. Pollution is  
foreign matter in a solid, liquid, or gaseous state that can reduce dielectric  
strength or surface resistivity. The following is a description of pollution  
degrees:  
Pollution Degree 1 means no pollution or only dry, nonconductive  
pollution occurs. The pollution has no influence.  
Pollution Degree 2 means that only nonconductive pollution occurs in  
most cases. Occasionally, however, a temporary conductivity caused  
by condensation must be expected.  
Pollution Degree 3 means that conductive pollution occurs, or dry,  
nonconductive pollution occurs that becomes conductive due to  
condensation.  
You must insulate signal connections for the maximum voltage for which  
the module is rated. Do not exceed the maximum ratings for the module.  
Do not install wiring while the module is live with electrical signals. Do not  
remove or add connector blocks when power is connected to the system.  
Avoid contact between your body and the connector block signal when hot  
swapping modules. Remove power from signal lines before connecting  
them to or disconnecting them from the module.  
Operate the module at or below the measurement category1 marked on the  
hardware label. Measurement circuits are subjected to working voltages2  
and transient stresses (overvoltage) from the circuit to which they are  
connected during measurement or test. Measurement categories establish  
standard impulse withstand voltage levels that commonly occur in  
electrical distribution systems. The following is a description of  
measurement categories:  
Measurement Category I is for measurements performed on circuits  
not directly connected to the electrical distribution system referred  
to as MAINS3 voltage. This category is for measurements of  
voltages from specially protected secondary circuits. Such voltage  
measurements include signal levels, special equipment, limited-energy  
parts of equipment, circuits powered by regulated low-voltage sources,  
and electronics.  
Measurement Category II is for measurements performed on circuits  
directly connected to the electrical distribution system. This category

NI SPEEDY-33 Functional Description and Interface  
DSP  
The digital signal processor on the NI SPEEDY-33 is a powerful  
floating-point, flexible, and easy-to-use processor designed by Texas  
Instruments.  
The VC33 DSP is capable of high performance mathematical operations.  
It is a 32-bit, floating-point processor manufactured in 0.18 μm  
four-level-metal CMOS (TImeline™) technology, and is part of the  
SM320C3xgeneration of DSPs from Texas Instruments.  
The VC33 DSP internal busing and special digital signal processing  
instruction set have the speed and flexibility to execute up to 150 million  
floating-point operations per second (MFLOPS). The VC33 DSP optimizes  
speed by implementing functions in hardware that other processors  
implement through software or microcode. This hardware-intensive  
Note Although this DSP is capable of 75 MIPS, 150 MFLOPS, the crystal driving the  
DSP on the NI SPEEDY-33 is slightly slower than what would be required to achieve this  
maximum speed, namely 14.7456 MHz as opposed to the maximum 15 MHz. This allows  
for specific desirable sample rates to be achieved for the A/D and D/A hardware described  
in the Stereo A/D, D/A (Analog Input, Analog Output) section. Refer to the Appendix A,  
Specifications, for information about DSP speed.  
The VC33 DSP can perform parallel multiply and ALU operations on  
integer or floating-point data in a single cycle. Each processor possesses a  
general-purpose register file, a program cache, dedicated ARAUs, internal  
dual-access memories, one DMA channel supporting concurrent I/O, and a  
short machine-cycle time, resulting in a high-performance, easy-to-use  
device.  
Typical signal processing applications are enhanced by the large address  
space, multiprocessor interface, internally- and externally-generated wait  
states, one external interface port, two timers, one serial port, and a  
multiple-interrupt structure. The VC33 DSP supports a wide variety of  
system applications from host processor to dedicated coprocessor.  
High-level language support is easily implemented through a register-based  
architecture, large address space, powerful addressing modes, flexible  
instruction set, and well-supported floating-point arithmetic.

NI SPEEDY-33 Functional Description and Interface  
Memory  
There are two types of available memory on the NI SPEEDY-33, on-chip  
memory and flash memory.  
On-Chip Memory  
The DSP uses on-chip memory for algorithms because of its fast speed.  
There are 136 KB of on-chip RAM that the DSP can access with zero wait  
states. This memory is used for both program and data space.  
Flash Memory  
The NI SPEEDY-33 includes flash memory that allows the device to be  
programmed and run in standalone mode without connection to a PC. This  
is essential for producing actual products or self-standing prototypes. Refer  
to the Flash Boot Jumper section for information on configuring the jumper  
to enable flash memory boot up for standalone mode.  
The flash memory is byte-wide and organized as 512 K × 8, with the DSP  
mapping it to a 512 K × 32 (2,048 KB) area, only able to read the lowest  
byte (upper 24 bits are not read by or written to the DSP). Refer to the Flash  
Write Enable Jumper section for information on jumper configurations for  
enabling or disabling flash memory write protection.  
Ports  
For a diagram of port locations on the NI SPEEDY-33, refer to Figure 2-1.  
PC USB Port  
The PC USB port (J8) connects the NI SPEEDY-33 (target) to a PC (host)  
with a standard USB cable. The NI SPEEDY-33 functions as a full-speed  
USB device when connected to the PC host. The PC USB port is a Type B  
USB port (peripheral USB port) and conforms to USB Specification 1.1.  
When the NI SPEEDY-33 is connected to the PC, the USB port supplies  
power to the device, eliminating the need for the power port (J10), as  
described in the Power Port section. When power is supplied to the device,  
the power LED lights.

The power port (J10) can supply the NI SPEEDY-33 with external power  
when operating the device in standalone mode, without being connected to  
the PC through USB. When power is supplied to the device, the power LED  
lights.  
The input voltage must be 9 VDC, at 500 mA, with the outside contact  
being ground and inner contact being positive VDC. An appropriate  
2.5 mm jack can be used in conjunction with a 9 V battery (pack) to  
optionally supply power for battery-powered applications. Refer to  
Appendix A, Specifications, for complete power supply specifications.  
Audio Stereo Input Port  
Audio input can be connected to the audio stereo input port (U11).  
Caution Ensure that line level audio signals are not connected to the audio input when the  
NI SPEEDY-33 is configured for microphone level. It is possible to damage the audio input  
circuitry by overdriving the input.  
If an external microphone is used, it should be capable of operating with a  
standard stereo jack; not all microphones will work in this fashion. Many  
PC microphones will not work because they require a DC voltage to be  
driven on one of the inputs. Traditional mono microphones generally work  
fine.  
It is important to ensure that the audio input level jumpers (J1, J2) setting  
is configured appropriately for microphone level or line level, depending  
upon the audio source connected to this port. Refer to the Audio Input Level  
Jumpers section for more information.  
Note The onboard microphones are disconnected by mechanical disconnect when an  
audio source is connected to the audio stereo input port.  
Audio Stereo Output Port  
The audio stereo output port (U14) can be connected to a set of stereo  
amplified speakers. Typical amplified speakers used for PC sound should  
provide good output. You also can plug external headsets to this port,  
although there is no hardware control over the output gain or signal level.

NI SPEEDY-33 Functional Description and Interface  
Onboard Microphones  
Two onboard microphones (U2 and U5) can be used in applications  
requiring audio input or involving audio signal phase difference  
measurements. When the microphones are used, the input gain level of  
each microphone should be set to the microphone level setting described  
in the Audio Input Level Jumpers section.  
Caution Ensure that line level audio signals are not connected to the audio input when the  
NI SPEEDY-33 is configured for microphone level. It is possible to damage the audio input  
circuitry by overdriving the input.  
The onboard microphones are directly connected to the audio input  
conditioning circuitry, unless an external microphone is connected at  
the stereo input port (U11), as described in the Audio Input Level Jumpers  
section. If an external microphone is connected, the onboard microphones  
are disconnected from the input circuitry by mechanical disconnect.  
Eight memory-mapped LEDs are located on the NI SPEEDY-33 for  
general-purpose output. The LEDs are enabled by writing a 1 to the  
appropriate bit of the LED port. The LED output state is echoed on pins on  
the simple expansion digital I/O connector (J11), as described in the Simple  
Expansion Digital I/O Connector section.  
Switch Input Port  
There are eight memory-mapped general-purpose switch inputs on the  
NI SPEEDY-33. These switch inputs are accessed by the DSP through  
reading the appropriate bit of the switch input port. The switch inputs are  
connected in parallel to pins on the simple expansion digital I/O connector  
(J11). All switches should be in the OFF (open) position when connecting  
the expansion digital I/O connector, as described in the Simple Expansion  
Digital I/O Connector section.

NI SPEEDY-33 Functional Description and Interface  
Stereo A/D, D/A (Analog Input, Analog Output)  
The 16-bit stereo audio CODEC included on the NI SPEEDY-33 allows  
for up to 48 kHz dual-channel sampling on the input signal. Software  
components are included in the LabVIEW DSP Module to allow 8 kHz,  
18 kHz, 24 kHz, 36 kHz, and 48 kHz sample rates to be used in  
applications.  
Refer to the Audio Input Level Jumpers section for information on jumper  
settings that configure the amount of gain, from the onboard or external  
microphones, applied to the input audio signals.  
I/O Connectors  
Simple Expansion Digital I/O Connector  
The simple 20-pin expansion header (J11) allows for easy interface to  
external hardware. The header includes power, ground, eight digital inputs,  
and eight digital outputs under DSP control.  
The eight input bits are co-mapped to the switch input port. The  
eight output bits are co-mapped to the digital output port LEDs, as  
described in the Digital Output Port LEDs section.  
If the input bits on this connector will be used by an external piece of  
hardware, the switch input port—described in the Switch Input Port  
section—must have all the switches set in the OFF (open) position  
(all switches up, away from device). An ON (closed) switch position  
(switch down, towards the device) will effectively short that specific input  
bit to ground. Switch 1 correlates to IN1 on the connector, switch 2  
correlates to IN2, and so on. The connector pinout is shown in Figure 2-4.

Jumpers  
Audio Input Level Jumpers  
The audio input level jumpers (J1, J2) control the amount of gain applied  
to the input audio signals.  
The microphone level setting has the highest gain for the onboard  
microphones (U2, U5), the line level setting has less gain and is appropriate  
and so on).  
These settings will affect the gain of the external audio source and should  
be left in the line level setting if an external microphone or audio source  
is used at audio stereo input port (U10), described in the Stereo A/D, D/A  
(Analog Input, Analog Output) section. Table 2-2 shows the possible audio  
input level settings.  
Caution Ensure that line level audio signals are not connected to the audio input when the  
NI SPEEDY-33 is configured in the microphone level setting. It is possible to damage the  
audio input circuitry by overdriving the input.
