San Jose, California-based Xilinx Inc, which claims to be the inventor of the field programmable gate array, has introduced the first members of its third generation XC4000: the XC4005, XC4006, XC4008 and XC4010 incorporate several system-level functions on-chip to provide the highest performance available in the industry, and says it has started shipping the XACT 4000, a completely redefined computer-aided engineering development system that delivers 100% placement and routing of designs: the first XC4000 devices have system speeds up to 60MHz and a density range of 5,000 to 10,000 usable gates and a 100% performance increase was achieved by integrating seven system features onto the chip for the first time – on-chip memory, high-speed counters and decoders and JTAG boundary scan logic; sampling first quarter, the first available device, the XC4005, with 5,000 usable gates, costs $192.50.
