Unformatted text preview: DSK Overview 1.2 DSK Overview Figure 1–1 depicts the block diagram of the TMS320C3x DSK hardware. The basic components are the TMS320C31 DSP, the TLC32040 AIC, expansion connectors, system clock, parallel printer port interface, and tri-color LED. The parallel printer port connects the DSK to a host PC and allows the TMS320C31 to communicate with PC programs. All of the signals for the ’C3x are routed to expansion connectors. The expansion connectors include four 32-pin headers, an 11-pin jumper block, and a 12-pin XDS510 header. The TLC32040 AIC interfaces to the TMS320C3x serial port. A jumper block allows removal of this connection to route the serial port to a DSK daughtercard that you supply. Two RCA connectors provide analog input and output on the board. Figure 1–1.
