Software environment for a multiprocessor DSP

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.

Quality assurance in scripting

Most scripting platforms ignore quality assurance issues for multimedia applications. Our authoring paradigm enables formal analysis, which lets developers explore all the different situations possible during the course of a user session and ensures that the needed responses have indeed been included in the script. We successfully analyzed games from a prototype interactive television (ITV) demonstration script. >
