有谁熟悉MIPS或PowerPC的嵌入式处理器?

兄弟我目前正在研究这个,有经验的朋友希望交流一下

请问斑竹，你现在研究的是哪家的ppc,我在学mpc860。希望有机会多探讨

正在分析IDT的MIPS处理器和PLX的IOP480,目前是要确定选型的方向,需要看很多资料,综合对比,比较累.

正在研究mpc8260多多指教

在网上看到的有关IBM embedded ppc的消息。
“Boost Embedded Application Performance with New IBM PowerPC Processors

EAST FISHKILL, N.Y., March 11, 2002...IBM today, introduced two
new fast, flexible, low-power PowerPC processors that will give
chip designers a richer mix of features for a broad set of
embedded applications. The new chips are a part of the IBM
PowerPC 4xx family of integrated 32-bit RISC processors and
manufactured on IBM\'s 0.18 micron SA-27e copper process
technology. They offer the extra horsepower necessary to improve
the performance of a variety of applications, including data
storage, imaging, Internet access devices and communication
products such as base stations, routers or gateways.

The IBM PowerPC 440GP is a superscalar processor with large
caches, a 128-bit CoreConnect bus and high performance
peripherals, including PCI-X bridge and DDR SDRAM controller. It
will be available in 400, 466, and 500 MHz frequencies, and
provides 1,000 MIPS performance at 500 MHz. The processor teams
with a high bandwidth 4.2 Gb/s on-chip CoreConnect bus, and off-
chip interfaces with peak bandwidths of 2.1 Gb/s to DDR memory,
and 1.1 Gb/s PCI-X, along with two Ethernets and several other
communications interfaces. This powerful processing engine fits
into a 25 mm package, offering a compact solution for dense
applications.

The IBM PowerPC 405GPr embedded processor is a pin-compatible
upgrade to the highly successful PowerPC 405GP and offers a new
level of performance. Processor speeds have reached 266, 333 and
400 MHz with a typical power dissipation of 1.3 watts for the 333
MHz processor. It also incorporates a PCI interface, an SDRAM
controller, a 64-bit on-chip CoreConnect bus, a Fast Ethernet
controller and more on-chip peripheral support.

IBM will showcase these new solutions in the Embedded Systems
Conference in San Francisco at the Moscone Convention Center
March 13-15 in booth 910-S, South Hall.
