Abstract :
An embedded multimedia system is being constructed to provide high-quality video and audio processing capabilities for desktop multimedia workstations. This versatile JPEG-based system is capable of sustaining a throughput of 2-Mbyte/s compressed data rate, which is a necessary condition for studio quality video and audio at the CCIR 601 resolution. The main design challenge is to methodologically evaluate critical data paths to ensure that the hardware system meets the periodic deadline of the isochronous multimedia data streams (e.g., 1/30 s/frame for motion video). The authors describe the system design objectives, system architecture, and preliminary results of performance analysis
