Real-time processing on configurable multimedia systems

This paper shows the actually measured response times that can be achieved with Linux configurations on Virtex processor+FPGA architectures, containing both hard PowerPC processors or soft Microblaze processors and FPGA fabric. How the various response times drive system design is shown in this paper. The trade-off between the part of an application that can be handled with a real-time operating system, a hard-coded software loop and accelerators configured in FPGA fabric. A system performing HDTV rate image processing will also be discussed
