Small board promises high-performance DSP

Critical Link has released the MityDSP-Pro, a high-end edition of its customizable MityDSP platform. The MityDSP-Pro features a Texas Instruments TMS320C6455 DSP clocked at 1.2GHz. This DSP gives the MityDSP-Pro five to six times the processing power of the original MityDSP. The MityDSP-Pro targets data- and processing-intensive applications including embedded radar control and signal processing, high data rate real-time DAQ, image processing, video processing and fine-tolerance manufacturing test and control.

The MityDSP-Pro integrates the TI C6455 DSP with a Xilinx XC3S2000 Spartan 3 FPGA, flash and DDR2 SDRAM, and includes support for four 1x Serial Rapid I/O links. The MityDSP-Pro is also available with the lower-cost TI TMS320C6454 processor, which supports CPU clock speeds up to 1GHz. The module is also available with a larger FPGA, up to a Spartan 4000 series.

In a typical implementation, Critical Link engineers work with their customers to create a production-ready I/O interface card to carry system interfaces driven by the MityDSP-Pro. The available interfaces include ADCs, DACs, Ethernet ports and GPIO.

The MityDSP-Pro is notable for its small size. This should speed productization for size constrained applications. It is also notable that previous generation MityDSPs used TI's floating-point C6711. Critical Link reports that floating-point emulation takes 3x more clock cycles than hardware floating-point, but that the much higher clock rate of the fixed-point DSPs more than makes up for the increased cycles.

The MityDSP-Pro standard module is priced at $1,295 in quantities of 100. The MityDSP-Pro module is also available in production quantities.
