Company Description:
The HHPC board is configured with four 80 MHz 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. 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. 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.
