Appendix B

DSP/BIOS

 

 

B.1 Introduction

COME readers are curious about DSP/BIOS, which is a real-time operating system specific to the Texas Instruments DSPs [93,94]. This appendix provides a short description of DSP/BIOS, and several projects intended to get you started in the DSP/BIOS environment.

B.1.1 DSP/BIOS Major Features

The major features of DSP/BIOS include:

• The scheduler and its associated thread classes provide a mechanism for arranging and controlling the software’s execution. The scheduler is preemptive, meaning that it will periodically interrupt the currently executing thread, determine what the highest priority thread is that is ready to execute, and start that thread running. One of the DSP’s hardware timers is ...
