Memory Block Size
TriMatrix memory provides three different memory sizes for efficient
application support. The large number of M512 blocks are ideal for
designs with many shallow first-in first-out (FIFO) buffers. M4K blocks
provide additional resources for channelized functions that do not
require large amounts of storage. The M-RAM blocks provide a large
single block of RAM ideal for data packet storage. The different-sized
blocks allow Stratix devices to efficiently support variable-sized memory
in designs.
The Quartus II software automatically partitions the user-defined
memory into the embedded memory blocks using the most efficient size
combinations. You can also manually assign the memory to a specific
block size or a mixture of block sizes.
