Abstract
To address the need for enhanced real-time analysis, Texas Instruments Inc. has developed a standard embedded infrastructure for its DSPs that provides unique visibility into real-time program execution. Integrated with TI's Code Composer Studio development environment, this infrastructure consists of two components: 1) DSP/BIOS, a tiny target-based run-time system that captures event and statistical information for the application and uploads it to the host (via a standard physical link such as JTAG) as the application executes in real-time; this DSP/BIOS system is integrated with the target application (C or DSP assembler); 2) Scope, a suite of host-based tools that allows designers to visually trace, monitor, and probe the DSP application as it executes in real time. Even after the Code composer debugger halts the program and assumes control of the target, information already captured through embedded DSP/BIOS instrumentation can provide valuable insight into the sequence of events that led up to the current point of execution.
