The TMS320C31 chip from Texas Instruments is ideal for DSP and Embedded System Applications. Its powerful instruction set, high speed number-crunching capabilities, and innovative architectures enhance the performance of DSP applications. Its JTAG IEEE 1149.1 emulation port and microcomputer/boot-loader function facilitate computer simulation, debugging, and embedded-system development. Up to date, the speed for this low-cost chip ranges from 27MHZ to 50MHZ.

At NSLS, we have incorporated an SN74ACT8990 test bus controller with an open-target-interfaced emulation porting kit to emulate and debug VME-bus based DSP applications, and AT-bus based embedded system developments. Some technical hardware/software details in implementing the emulation will be discussed. Some commercial scan-path emulators for TMS320C31 will be listed as considerations for time frame, finacial plan, and design needs.
