Abstract

The invention relates to a switchboard based extensible DSPEED-DSP_Q6474 signal processing board, which belongs to the field of high-speed real-time signal processing. The processing board comprises a single-core DSP processing node, four three-core DSP processing nodes, an FPGA (Field Programmable Gate Array) processing node, a serial Rapid IO (Input-Output) switchboard module and a CPCI 6U standard board type, wherein the single-core DSP processing node consists of a TMS320C6455 and a set of DDR2 SDRAMs of which the volume is 512MB; the three-core DSP processing node consists of a TMS320C6474 and a set of DDR2 SDAMs of which the volume is 512MB; and the FPGA processing node consists of an XC5VSX95 or an XC5VLX110T and two sets of DDR2SDRAMs of which the volume is 512MB. The invention solves the problems of small data exchange bandwidth between the traditional high-speed real-time signal processing board processors, non-uniform interface protocols and poor intra-board extendibility.

Description

Technical field [0001] The invention relates to a switch-based extensible DSPEED-DSP_Q6474 signal processing board, which belongs to high-speed real-time signal processing and related fields. Background technique [0002] High-speed real-time signal processing boards are mainly used in embedded applications with large data volumes, intensive calculations, and strong real-time performance, such as radar signal processing, image processing, and wireless base stations. In these applications, high-speed real-time signal processing boards require not only powerful computing capabilities and large-capacity data cache capabilities, but also large-bandwidth data exchange capabilities between processors to achieve high-efficiency parallel processing. Broadband inter-board interface to improve the scalability of the board. [0003] At present, most high-speed real-time signal processing boards have small computing power and cache capacity, small data exchange bandwidth between processors, i...
