JTAG interface system for communicating with compliant and non-compliant JTAG devices

Abstract: A system and method for using standard JTAG protocol for testing protocol compliant and non-protocol compliant digital devices without altering the JTAG protocol or the non-compliant device. A specialized Test Access Port Controller controls and monitors the states applied to the non-compliant device in order to eliminate the PAUSE state in the non-compliant device and to limit the Run-Test/Idle state to one clock period.

Implementing a Hardware Monitor Using the TMS320C40 Analysis Module and JTAG Interface for Performance Measurements in a Multi-DSP System

Abstract: This application report describes the design and implementation of a hardware monitor that provides information from the processor level up to the application level. It uses the on-chip analysis module of the Texas Instruments (TI) TMS320C40 digital signal processor (DSP) and a boundary-scan technique according to the IEEE 1149.1 JTAG-standard. The monitor can be used for both single processor and multiprocessor systems. There is no limit on the number of processors monitored. An instrumentation of the software running on the DSPs is not required. The monitor influences the application in terms of runtime but does not change the order of events. This document was an entry in the 1995 DSP Solutions Challenge, an annual contest organized by TI to encourage students from around the world to find innovative ways to use DSPs.
