Tutorial IND2A: Embedded Systems Design with Xilinx Virtex-5 Series FPGA

摘要

Embedded systems design is a hot application field which merges logic design and processor-based hardware development in a single or few chips solution. In recent years, embedded applications have emerged at a faster rate and used in every field of one can think of ranging from household products such as microwaves, to automotive products such as air bags sensing and control, to industrial robots which employ distributed processing and coordination. Various technologies have been used in the development of embedded systems; microcontroller, DSP processor, ASIC, and now FPGA. Embedded systems development involves hardware and software components development as they coexist in such systems. The software is unique to a system and varies in complexity from system to system and application to application. This peculiar characteristic makes the system development unique and challenging. Typically, such system development involves another system on which design and development takes place. Field Programmable Gate Arrays (FPGA) from Xilinx, through generations of development, have enlarged applications area envelope. With the introduction of Virtex-II Pro, Xilinx entered embedded processing area. Through the rigorous development of supporting tools and introduction of Virtex-4, Xilinx positioned itself as a major player in the embedded applications area. In order to gain higher performance, Virtex-4 architecture was radically improved and Virtex-5, introduced in mid-April, pushed the envelope further. The trend is to improve silicon efficiency by porting widely used functions in hard core. Xilinx FPGA families carry hard core and soft core processors. The development kits provide hardware/software tools which facilitate implementation of functions, which are not yet realized, by embedding them as soft intellectual property in the FPGA fabric. In this tutorial, we will show how Xilinx Virtex-5 FPGAs can be used in embedded applications. The strengths of Xilinx FPGAs and the supporting development tools will be described. A demonstration will be provided to show the ease of design and development of a complete system.
