Hypersignal®-Macro development
software (see below) 16-bit HPI host-port, TDM / buffered serial port, external interrupt, and reset signals available at module edge Cookie EEPROM with I2C serial interface stores host configuration data
Optional boot / FLASH EEPROM stores boot or program code, configuration and other non-volatile application data JTAG signals are chained between DSPs and available at module edge 4-channel audio CODEC SODIMM module also available
Applications
Applications for SigC67xx modules include
radar,
sonar, control systems,
medical, base stations, high precision FFT, wavelet, and other transform processing, VoIP (voice-over
Internet protocol) networking functions, VoDSL (voice-over DSL), Internet routing,
multiple-channel speech or audio code / decode (e.g. G.729A or MELP speech compression and MP3
audio compression), moderm banks, echo cancellation, and speech recognition.
The module approach is particularly well suited to providing a scalable solution for defense
electronics, telecom, and Internet equipment applications that require a high number of DSP
devices. For example, channel capacity is highly configurable.
Advantages
SigC67xx-SODIMM module, offers Quad C67xx processing power in small package, provides multiprocessor DSP solutions for defense electronics,
telecom, Internet routing, and network infrastructure applications. The modular approach to
multiple DSP processing offers higher density and performance, lower-cost, and several
advantages for OEM products:
base-board design is simplified and fabrication risk is decreased modules can be upgraded easily, as faster and more capable Texas Inst. DSP devices
become available for custom applications, it is straightforward to specify a module with fewer
processors and more memory, or vice versa SigC67xx modules are supported by standard, off-the-shelf software tools,
including DirectDSP, Real-Time Composer™, and Hypersignal-Macro software
Processors
The Texas Instruments C67xx 32-bit floating-point DSP family offers high performance,
flexible external memory interface, and a rich set of onchip peripherals.
The TMS320C6711, C6712, and C6713, including 150 MHz C6711B, 200 MHz C6711C (available
4Q 2003), 225 MHz C6713, and 100 MHz C6712 digital signal processors range from 100 to 225 MHz
(600 to 1350 peak MFLOPS, or 240 to 540 general-purpose code MFLOPS) in processing capability.
They offer a complete set of onchip peripherals depending on processor type, including serial
ports, host port, PLL, timers, DMA channels, and up to 128k x 32 onchip memory.
Cost/performance tradeoff possibilities range from the C6711, an extremely cost effective
solution, to higher performance processors, such as the C6713.
Boot / FLASH EEPROM
The SigC67xx-SODIMM module contains a 4M x 16 boot / FLASH EEPROM that stores boot or
program code, configuration and other non-volatile application data.
Host Interface Logic
The SigC67xx-SODIMM module contains PLD logic that multiplexes module edge HPI (Host Port
Interface) signals for multiple DSPs and allows one or a combination of DSPs to be accessed
simultaneously during host writes (broadcast mode), and individually during host reads.
Broadcast mode includes onchip memory block writes, DSP program (COFF) file download, reset,
run, and external interrupts.
TDM Routing Logic
The SigC67xx-SODIMM module contains PLD logic that allows flexible serial port/TDM routing
capabilities. For example, all DSPs can see the same TDM bus, or be routed to separate serial ports at the module edge.
Also, DSPs may communicate to each other via high-speed synchronous serial port. This flexibility allows TDM streams to be tailored to fit the natural architecture of the C67xx DSP family and facilitate DSP software development.
