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
SM320C3x

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
approach provides performance previously unavailable on a single chip.

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.

™

generation of DSPs from Texas Instruments.

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.

states. This memory is used for both program and data space.

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.

Chapter 2 NI SPEEDY-33 Functional Description and Interface

Power Port

Caution Do not connect the power source to the power port while the NI SPEEDY-33

device is connected to the PC.

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 User Manual 2-6 ni.com

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.

Digital Output Port LEDs

Chapter 2 NI SPEEDY-33 Functional Description and Interface

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.

Chapter 2 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.

The digital I/O signals are 3.3 V, but the inputs are 5 V tolerant. Although
not required, pin 20 (ResetLow) can be driven low to reset the DSP; it is
pulled high by the NI SPEEDY-33.

Standard Expansion Analog I/O Connectors

A set of two connectors, J4 and J6, make up the standard expansion analog
I/O connectors, that can be used for optional daughter modules. The
daughter modules can be used for applications requiring different A/D
and/or D/A functionality than that provided by the standard 16-bit stereo
CODEC normally found on the NI SPEEDY-33.

Refer to the Connecting Accessories to the NI SPEEDY-33 section for
information on NI and third-party daughter modules for use with the
NI SPEEDY-33.

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
for the line level audio interface (for example, CD players, MP3 players,
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.
