Implementing FIFO Buffers
While the small M512 memory blocks are ideal for designs with many
shallow FIFO buffers, all three memory sizes support FIFO mode.
All memory configurations have synchronous inputs; however, the FIFO
buffer outputs are always combinatorial. Simultaneous read and write
from an empty FIFO is not supported.
Depending on the TriMatrix memory mode, independent, input/output,
read/write, and/or single-port clock modes are available.
shows the clock modes supported by the TriMatrix memory modes.
Independent Clock Mode
The TriMatrix memory blocks can implement independent clock mode
for true dual-port memory. In this mode, a separate clock is available for
each port (A and B). Clock A controls all registers on the port A side,
while clock B controls all registers on the port B side. Each port also
supports independent clock enables and asynchronous clear signals for
port A and B registers.
