DSP/BIOS is a scalable real-time kernel. It is designed to be used by applications that require real-
time scheduling and synchronization, host-to-target communication, or real-time instrumentation.
DSP/BIOS provides preemptive multi-threading, hardware abstraction, real-time analysis, and
configuration tools.
