General Description
Xilinx developed the System Advanced Configuration Envi-
ronment (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.
ACE Flash
CompactFlash Storage Device
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 uses
CompactFlash.
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).
