Capable of working as a high-powered on-board compute engine or as a high-performance bridge to external SHARC processors needing to link to the PCI bus, IXZPMC4 Quad SHARC PCI Mezzanine Card (PMC) delivers 480 MFLOPS of computing power completely within the host board environment and has a PCI-SHARC throughput of 132 MB/s (80 MB/s sustained) on a 32-bit, 33-MHz PCI bus. The PMC's computing power effectively reduces the delay between data acquisition and processing by eliminating the need to perform off-board data transfers to another DSP engine. On baseboards containing two PMC slots, almost a full GFLOP of computational power can be delivered before resorting to off-board units for additional processing power.
