The ever-increasing performance requirement of real-time signal processing applications drives the integration of emerging interconnect technologies with high-performance processors and ADCs. In order to construct a scalable and high-performance signal processing system, we have developed two kinds of flexible signal processing modules based on high performance ADC, heterogeneous processors and the RapidIO interconnect technology. The receiver module mainly consists of two 10 bits 2 Gsps ADCs, one TMS320C6455 and one XC5V95T FPGA. And the processing module is composed of four TMS320C6455 and one XC4VSX55. In this paper, a heterogeneous massive multi-processor system consists of one receiver module and two processing module aggregated by the RapidIO is introduced which may act as dual-channel wideband receiver. And its application in multi-channel receiver is discussed.
