ADSP-21060 Hammerhead DSP PCI Board

BittWare’s Hammerhead-PCI (HHPC) board matches the processing power of the Analog Devices ADSP-21160 SHARC® processor with a 64-bit, 66 MHz PCI interface. The board features four ADSP-21160 processors, 64-256 MB of SDRAM, 2 MB of FLASH memory and two PMC mezzanine sites.

The HHPC 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 minimum processor overhead.

ADSP-21060 SHARC DSPs

The HHPC board is configured with four 80MHz ADSP-21160 processors, each with 4 Mbits of on-chip dual-ported SRAM. The ADSP-21160 DSPs are code-compatible with the ADSP-2106x SHARC DSPs, making it easier to integrate existing code. The four ADSP-21160s 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 DSPs. For additional I/O, each processor also has four flags, three interrupts, six link ports, and two serial ports.

PMC Sites

The HHPC board features two PMC (PCI Mezzanine Card) sites. One PMC site allows you to attach a standard PMC module to the board, adding I/O or additional processors and memory. The other PMC site has back panel access and functions as both a standard PMC and a proprietary interface for BittWare's PMC+ I/O modules. It features PMC+ extensions that allow you to attach PMC+ modules for low-latency, high-performance I/O via four 80 MB/s link ports and one 40 Mb/s serial port.
