Abstract:This design uses five interlinked DSP chips, which based on fixed-point TMS320C64x of TI, to implement processing function of channel data in wireless base station. MPC8260 completes initial configuration and program loading of interlinked system. This article has introduced in detail the resolution about clock of interlinked DSP system, the ID number setting of each interlinked DSP, and the design of JTAG chain which added for the test convenience.
