Loongson cpu

Main Features:

The Loongson2F is an evolution of the Loongson2E with the enhanced I/O and memory accessing bandwidth and a software work frequency changing scheme and compatibility to MIPS64. The Loongson2F integrates a high performance Loongson2 CPU core, DDR2 memory controller, PCI/PCI-X interface, Local bus, interrupt controller and video acceleration unit.

With low power consumption, Loongson 2F performances well and widely used in embedded and desktop fields as well as in loongson education computers.
