fast, flexible solution embedded developers PowerPC 405GP 405GPr family 32-bit RISC processors designed provide flexible, fast timeto-market hardware solution satisfy demands high-performance embedded applications. Implemented scalable PowerPC architecture, 405GP 405GPr processors maintain code compatibility with other PowerPC processors ease migration faster time-to-market.
optimized balance performance, power, features makes them ideal solutions communication, data storage, pervasive computing applications. 405GP 405GPr processors support speeds 266MHz 400MHz respectively. Both incorporate rich features, such interface, SDRAM Controller,
wide variety packaging options complements speed flexibility PowerPC embedded processor family.
64-bit on-chip CoreConnect bus, Ethernet other on-chip peripheral support, CodePack code compression engine. addition, power management features, small form factor, power consumption make processor family ideal platform applications ranging from networking video. Performance tackle most demanding applications PowerPC 405GP 405GPr embedded cores incorporate features enable high performance without increasing chip size power. 4-KB on-chip SRAM stores critical code data.
five-stage pipeline increases throughput enables speeds 400MHz. includes fetch, decode, execute, write-back, load writeback stage. single-issue execution unit especially useful switching routing equipment where real-time operation critical. unit, which contains register file, arithmetic logic unit (ALU) multiply-accumulate (MAC) unit, performs integer instructions hardware. register file, comprised thirty-two 32-bit general purpose registers (GPR), enables either load store operation execute parallel with operation. memory management unit (MMU) provides address translation, flexible memory protection, storage-attribute control. supports multiple page
sizes well variety storage-protection attributes access-control options. Multiple page sizes improve memory efficiency minimize number buffer misses. Robust features provide design flexibility rich additional features complement core functions.
