Power savings with multi-execution CPU performance

The Freescale Semiconductor MPC8640D dual-core processor is a lower-cost version of the established MPC8641D, delivering a pin-compatible alternative that also consumes up to 21% less power.

A compatible single-core processor, the MPC8640, is also available, as a lower-cost, lower-power alternative to the existing single-core MPC8641.

The MPC8640D and MPC8640 both feature Freescale’s e600 CPU core, which has 11 independent execution units including a floating-point unit, branch-processing unit and four integer units. There are also three register files, and the core is capable of completing up to three instructions per cycle. In addition, the core embeds the industrybenchmark 128-bit AltiVec vector-processing engine, which typically delivers a 2x to 12x performance increase.

High-speed I/O connectivity complements these high processing resources, including an integrated DDR1/DDR2 memory controller, two PCI Express® and RapidIO® controllers and four gigabit Ethernet controllers. By also integrating northbridge and south-bridge functionality, both processors are capable of replacing multiple conventional chips in applications where a high performance-to-power ratio is critical.

The MPC8640D and MPC8640 also feature internal core-to-peripheral connections, saving board designers from the challenges of laying out high-speed parallel buses.
