Abstract :
In this paper, we describe the software environment for Daytona, a single-chip, bus-based, shared-memory, multiprocessor DSP. The software environment is designed around a layered architecture. Tools at the lower layer are designed to deliver maximum performance and include a compiler, debugger, simulator and profiler. Tools at the higher layer focus on improving the programmability of the system and include a run-time kernel and parallelizing tools. The run-time kernel includes a low-overhead, preemptive, dynamic scheduler with multiprocessor support that guarantees real-time performance to admitted tasks
