PMC-Sierra Unveils Third Generation Multiprocessor

PMC-Sierra announced its third generation highly integrated 64-bit MIPS-Powered multiprocessor designed for networking, storage and communications applications such as enterprise routers, storage systems and DSLAMs. The new processor integrates two newly designed 1.8 GHz E11K CPU cores with multiple high-speed memory and I/O interfaces, including dual DDR2, dual PCI Express, quad Gigabit Ethernet ports, and HyperTransport. The dual 64-bit DDR2 memory controllers support frequencies up to DDR2-800, and support 8-bit ECC. The PCI Express interfaces support either dual 4-lane interfaces or a single 8-lane interface. The quad Ethernet interfaces support automatic assignment into 8 queues per port and perform HW checksum assist. The HyperTransport interface runs up to 600 MHz link frequency, providing up to 10 Gbs of full duplex bandwidth. All of the I/O interfaces support Direct Deposit, which allows external peripherals to write directly into the L2 cache, avoiding costly external memory accesses and greatly increases system performance. http://www.pmc-sierra.com/processors/
