基于PowerPC的嵌入式系统硬件设计

在本设计中,使用了Motorola公司的RISC处理器PowerPC7410作为核心处理器.该处理器是新一代G4处理器,具有高性能和低功耗的特点,外接一个2Mbytes L2 Cache作为二级缓存,以提高运算速度.以Tundra公司为PowerPC专门设计的桥芯片/存储器控制器Tsi107作为北桥芯片,利用60X总线和PowerPC7410相接,用以把60X总线信号转化为PCI总线信号,并管理Flash和SDRAM.此设计充分利用60X总线高数据传输速率和优秀的连接性能,发挥了MPC7410的高可靠性和强大的处理能力,使该硬件平台具有优良的性能.

Hardware Design of Embedded System Based on PowerPC Processor

In this design, the system uses PowerPC Processor 7410 of Motorola as the core processor. It is new generation PowerPC G4 processors with the character of high performance and low power- consuming. Connect the L2 cache to it to improve the speed. Use Tsi107 as north bridge chip. It is a bridge chip/memory controller designed by the Tundra corporation adapt to the PowerPC, uses 60X bus to connect it to MPC7410. Fully use the high peed and good connectable capability of 60X bus, the high credibility and powerful processing capability of MPC7410 in order to fully take the system have high perfonmance.
