Hammerhead-3U-cPCI
Last updated: November 22, 2005
Company Description:
BittWare´s Hammerhead-3U-cPCI (HH3U) packs the processing power of four ADSP-21160 SHARC DSPs and the speed of a 66 MHz PCI interface on a 3U CompactPCI board. The HH3U is configured with four 80 MHz ADSP-21160 DSPs, each of which feature 4 Mbits of dual-ported on-chip SRAM. The ADSP-21160s are code-compatible with the ADSP-2106x SHARC DSPs, making it easier to integrate existing code. The four ADSP-21160 DSPs share a common 40 MHz, 64-bit cluster bus, which gives them access to the board´s SDRAM, the PCI bus interface, and the other three SHARC processors. For additional I/O, each processor also has four flags, three interrupts, six link ports, and two serial ports. The HH3U incorporates BittWare´s SharcFIN ASIC, which flexibly interfaces the ADSP-21160 DSPs to the 64-bit, 66 MHz PCI bus, the SDRAM, the FLASH memory, and a peripheral bus. It also provides a feature-rich set of DMA functions and interrupt options to support very high-speed, real-time data flow with a minimum of processor overhead. A back panel connector (P2) on the HH3U is used for back panel I/O, providing four link ports, a serial TDM bus, and an RS-232 connection. The HH3U features a 64-bit, 66 MHz PMC+ site.
