System ACE CF Controller
The System ACE CF controller manages FPGA configura-
tion data. The controller provides an intelligent interface
between an FPGA target chain and various supported con-
figuration sources; it can target multiple FPGA devices
using JTAG at a selectable throughput of up to 16.7
The directory structure used by the System ACE CF con-
troller enables it to support both CompactFlash and Hitachi
Microdrive devices through the CompactFlash port.
The MPU interface has access to the CompactFlash port,
the Configuration JTAG port, and local control/status fea-
tures. The Test JTAG port is used when doing Bound-
ary-Scan testing of the target FPGA chain or the System
ACE CF controller. Details about each interface are dis-
cussed below.
