Engineers at Ixthos Inc. of Leesburg, Va., are introducing their Quad SHARC PCI Mezzanine Card (PMC) that can work as a single-board computer or as a bridge to external SHARC digital signal processors (DSPs) that must communicate with the PCI bus. The new mezzanine-board DSP, called the IXZPMC4, delivers 480 million floating point operations per second of power. The board has four Analog Devices SHARC DSPs and has a PCI-SHARC throughput of 123 megabytes per second on a 32-bit 33MHz PCI bus. The board has 16 megabits of flash memory, 32K-by-32 dual-port SRAM, 2 megabytes of SRAM or 32 megabytes of DRAM, SHARC DSP support software, and costs $6,250.
