The PowerPC® 440GP embedded processor offers exceptional performance, design flexibility, and robust features geared to demanding networking, storage, and other embedded applications. With speeds of up to 500MHz, PowerPC Book E architecture, and a rich peripheral mix, PowerPC 440GP processors are ideally suited for a wide range of high-performance applications.

AMCC's advanced 0.18-micron CMOS copper process technology and an innovative design provide low power dissipation and a small footprint. Application code compatibility with other PowerPC processors enables manufacturers to bring products to market quickly and at a low cost to satisfy changing needs. High integration, including on-chip SRAM and robust peripheral support, can further simplify board design and help reduce manufacturing costs.

The leadership performance of the PowerPC 440 core derives from AMCC's state-of-the-art CMOS technology applied to embedded-application requirements. The PowerPC 440 superscalar core incorporates a 7-stage pipeline and executes up to two instructions per cycle, enhancing overall throughput. The core's large data cache (32K) and instruction cache (32K) are 64-way set associative, with versatile configurations to enhance performance tuning.

The memory management unit (MMU) allows the software developer to configure cache regions in one of three modes to allow application optimization: locked regions can be used for low-latency code or interrupt service routines; transient regions handle use-once data without disturbing the whole cache; and normal regions, which use typical least-recently-used (LRU) algorithms.
