Xilinx developed the System Advanced Configuration Environment (System ACE) family to address the need for a space-efficient, pre-engineered, high-density configuration solution for systems with multiple FPGAs. System ACE technology is a ground-breaking in-system programmable configuration solution that provides substantial savings in development effort and cost per bit over traditional PROM and embedded solutions for high-capacity FPGA systems. The System ACE family combines Xilinx expertise in configuration control with industry expertise in commodity memories. The first member of the System ACE family uses CompactFlash. As shown in Figure 1, the System ACE CompactFlash solution is a chipset, consisting of a controller device (ACE Controller) and a CompactFlash storage device (ACE Flash).
