General Embedded Processing System Based On Blackfin

Entered for the 21st century, the digitized tide has rolled up, the numerical information technology and the network technology have been rapidly developed, Embedded System widely apply to the people's produces and daily lives, and the request for the networking as well as the transmission standard multiplicity and the real-time application was more and more high. Obviously, traditional construction DSP and the RISC controller and its correlation products have already could not satisfy this request.The Blackfin processor is the new generation Embedded processor, which is developed by the American Analog Device limited company (ADI) with Intel, the first section fourth generation of DSP product, useing the brand-new MSA construction. The Blackfin processor and its extends the product are suit to the application which require lowr power dissipation, the high performance, the low cost, and the high operation ability and the application of quite high audio frequency, video frequency and communication system.The present paper's research content is uses series DSP of blackfin's characteristic such as high performance, low power dissipation and support dynamic power source management, establishes a High speed general embedded processing system. Paper main work:1: The Embedded-like characteristic and the development tendency have been carried on the discussion, and have determined the system core processor from the hardware platform and the software two aspects;2: The hardware system design based on blackfin 533 embedded system, the motherboard design and the debugging, fully considers the low power dissipation and the modular design consideration thought in the design.3: The IDE hard disk debugging and Embedded FAT32 filing system design, not only realizes the hard disk read-write, moreover has designed an general FAT32 filing system, the procedure is succinct, the probability is high, may be insert to the general operating system, takes the large capacity data management.4: High speed USB2.0 connection chip hardware design, firmware and WDM actuation design.
