DSK Overview
1-3 Introduction
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 expan-
sion 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 daughter-
card that you supply. Two RCA connectors provide analog input and output on
the board.
