The AMCC PowerPC 440GR processsor can run on Embedded Planet's EP440C single-board computer.

With speeds of up to 667MHz, support for DDR memory, ethernet and NAND flash interfaces, low power dissipation and a small footprint, the PowerPC 440GR embedded processor is ideally suited to a wide range of high-performance applications, including networking and storage. The 440GR is an excellent choice for 405xx users requiring additional performance or looking to upgrade to DDR memory.

To enhance overall throughput, the PowerPC 440 superscalar core incorporates a 7-stage pipeline and executes up to two instructions per cycle. Its large 32KB data cache and 32KB instruction cache are 64-way set-associative. Versatile configurations enhance performance tuning while optional parity protection preserves data integrity. For additional system performance, the PowerPC 440 core includes dynamic branch prediction and 24 digital signal processing (DSP) instructions, as well as non-blocking caches that can be managed in either write-through or write-back mode.
