Applied Micro Circuits Corp. announced the newest member of its embedded processor family, the PowerPC 460GTx.

Based on the Power Architecture standard, the PowerPC 460GTx processor combines a performance optimised PowerPC core with a high-bandwidth memory and I/O sub-system. The PowerPC 460GTx provides a high-performance migration path for customers using the AMCC PowerPC 440GX and 460GT processors.

The PowerPC 460GTx offers advanced features, including four Gigabit Ethernet ports with TCP/IP assist, 801.p- and q-compatible QoS, encryption/decryption engine, high-performance memory controller and high-speed I/O sub-system. The combination of these features is designed to meet the demanding requirements of the networking, wireless infrastructure, and general-purpose control applications.

The PowerPC 460GTx embedded processor features a PowerPC superscalar CPU core with clock frequencies ranging from 800MHz to 1.4GHz and performance of 2DMIPS/MHz (2800DMIPS at 1.4GHz). The PowerPC 460GTx also contains a 512KB level 2 cache, DDR2-800 SDRAM controller, and a high-bandwidth, multi-channel DMA controller. To support connectivity to the highest performance ASIC and FPGA devices, the 460GTx includes an 8-lane Gen 2 PCI Express interface; this interface can be bifurcated into two independent 4-lane Gen 2 PCI Express interfaces.
