Abstract

Abstract: The FPGA (Field Programmable Gate Array) of recent years has opened newer design possibilities of moving software into hardware. This paper is studied at two cases of transferring functionality from software into hardware. The paper describes the VCB (Virtual Communication Bus) concept and hardware tasks. The approach with VCB is focused today on existing systems with a main processor and slave processors or DSP (Digital Signal Processors). The first approach is to reduce the system load from the VCB bus and the second phase will be to eliminate the slave processors and move them to hardware tasks implemented in FPGA. This means that a hardware task can consist of 1000 pages of C code. The hardware tasks will reduce the response time and make the system more time-deterministic.
