System ACEtechnology is a ground-breaking in-system programmableconfiguration solution that provides substantial savings indevelopment effort and cost per bit over traditional PROMand embedded solutions for high-capacity FPGA systems.The System ACE family combines Xilinx expertise in config-uration control with industry expertise in commodity memo-ries. The first member of the System ACE family usesCompactFlash.As shown in Figure 1, the System ACE CompactFlash solu-tion is a chipset, consisting of a controller device (ACE Con-troller) and a CompactFlash storage device (ACE Flash).0System ACE CompactFlash SolutionDS080 (v1.5) April 5, 200200Advance Product SpecificationRFigure 1: System ACE ChipsetInterface to FPGA Target Chainfrom CompactFlash, MPU, or Test JTAG PortACE FlashCompactFlash Storage DeviceDS080_01_032101128 Mbits or 256 MbitsSystem ACE Controller DeviceSystem ACE CompactFlash Solution2 www.xilinx.com DS080 (v1.5) April 5, 20021-800-255-7778 Advance Product SpecificationRFigure 2 shows that the ACE Controller contains multipleinterfaces, including CompactFlash, MPU, and JTAG, toallow for a highly flexible configuration solution. For addedflexibility, a CompactFlash or IBM Microdrive storage devicesuch as the Xilinx ACE Flash card can be used to store mul-tiple bitstreams, with a capacity of up to 256 Mbits. Thecombination of the ACE Controller and a standard Com-pactFlash or IBM Microdrive storage device delivers a pow-erful configuration solution for high-density FPGA systems.ACE Flash Memory CardThe Xilinx ACE Flash memory card is a CompactFlashsolid-state storage device that complies with the PersonalComputer Memory Card International Association ATA(PCMCIA ATA) specification. The ACE Flash card is avail-able in two densities: 128 Mbits and 256 Mbits. This cardcontains an on-card intelligent controller that managesinterface protocols, data storage and retrieval, ECC, defecthandling and diagnostics, power management, and clockcontrol. Using commercially available, low-cost peripheral devices,the ACE Flash card can be programmed
