A real-time TMS320C40 based parallel system for high rate digital signal processing

The authors present the design and development of the TMS320C40 Parallel Processing Application Module (PPAM), a high-rate, parallel processing system for real-time digital signal processing applications. The PPAM is a stand-alone system, consisting of a four TMS320C40 board with analog interface, parallel run time support library, an SCSI port, and an IEEE JTAG compatible parallel processing emulation board. The total processing power of the system is 200 MFLOPS and it has 1.1 billion total operations/s performance with a peak interprocessor communication rate of 3.84 Gb/s. As examples, the performance of the PPAM is benchmarked by the implementation of a real-time multichannel echo canceller, an adaptive recursive least square lattice line enhancer, and the JPEG standard for image compression
