System ACE CompactFlash Solution
Write Data Buffer Control Flow Process
The control flow process for writing to the data buffer is
shown in
is implemented as a 32-byte (16-word) deep FIFO that is
aliased across a range of MPU byte addresses (40h
through 7Fh) in order to facilitate burst transfers across the
MPU interface. Sector data is written to the data buffer by
first waiting for the buffer to become ready (i.e., empty of
Microprocessor (MPU) to Configuration JTAG (CFGJTAG) Setup
This setup provides an MPU to CFGJTAG communication path. The data configures the FPGA system through JTAG via the
Configuration JTAG Port.
The System ACE CF controller handles all necessary steps to perform configuration using the MPU communication path to
the target system.

any sector data), as shown in
buffer is ready, then all 32 bytes can be written to the buffer
to alternating even and odd byte addresses. Writing to an
odd byte address while in BYTE mode causes the FIFO to
increment the data word to the next available word in the
FIFO. Writing to any data buffer address while in WORD
mode will cause the FIFO to increment.
