Highlights
Delivers 400MHz 500MHz performance high-speed embedded designs 32-bit implementation Book Enhanced PowerPC® architecture State-of -the-art peripherals including SDRAM PCI-X Incorporates performanceenhancing features, including superscalar operation, large caches, high-speed CoreConnectbus technology Offers power dissipation small form factor high-density power-conscious applications Provides application code compatibility with other PowerPC processors IBM's advanced 0.18-micron CMOS copper process technology innovative design provide power dissipation small footprint. Application code compatibility with other PowerPC processors enables manufacturers bring products market quickly cost
satisfy changing needs. High integration, including on-chip SRAM robust peripheral support, further simplify board design help reduce manufacturing costs. PowerPC Core: designed high performance leadership performance PowerPC core derives from IBM's state-of-the-art CMOS techAdvanced technology most demanding networking storage applications PowerPC 440GP embedded processor offers exceptional performance, design flexibility, robust features geared demanding networking, storage, other embedded applications. With speeds 500MHz, PowerPC Book architecture, rich peripheral mix, PowerPC 440GP processors ideally suited wide range high-performance applications. memory management unit (MMU) allows software developer configure cache regions three modes allow application optimization: locked regions used low-latency code interrupt service routines; transient regions handle use-once data without disturbing whole cache; normal regions, which typical least-recently-used (LRU) algorithms. nology applied embedded-application requirements. PowerPC superscalar core incorporates 7-stage pipeline executes instructions cycle, enhancing overall throughput. core's large data cache (32K) instruction cache (32K) 64-way associative, with versatile configurations enhance performance tuning.
also supports multiple page sizes, further contributing PowerPC core's memory efficiency maximizing translation lookaside buffer (TLB) hits. added system performance, PowerPC includes dynamic branch prediction, instructions, non-blocking caches that managed either write-through write-back mode. Wide data paths simultaneous reads writes boost throughput PowerPC 440GP CoreConnect 128-bit Processor Local (PLB) separate read write data buses that offer 4.2GBps on-chip bandwidth (peak). With 36-bit address path, offers 64GB memory addressability. integrated performance monitor enables performance tuning maximize on-chip resource utilization. 32-bit On-Chip Peripheral (OPB) collects less demanding devices improve utilization. Book Enhanced PowerPC Architecture Book Enhanced PowerPC architecture features increased architectural flexibility optimized embedded applications. adaptable memory management features robust debug capabilities geared real-time other highperformance operating environments. Book PowerPC architecture addresses requirements embedded applications while providing application code compatibility with current PowerPC applications.
