TriMatrix
embedded SRAM to efficiently address the needs of Stratix
designs. TriMatrix memory includes 640-bit memory logic array blocks
(MLABs), 9-Kbit M9K blocks, and 144-Kbit M144K blocks. The MLABs
have been optimized to implement filter delay lines, small first-in
first-out (FIFO) buffers, and shift registers. You can use the M9K blocks
for general purpose memory applications, and the M144K blocks are
ideal for processor code storage, packet buffering, and video frame
buffering.
You can independently configure each embedded memory block to be a
single- or dual-port RAM, FIFO, ROM, or shift register via the Quartus
MegaWizard. You can stitch together multiple blocks of the same type to
produce larger memories with minimal timing penalty. TriMatrix
memory provides up to 20,491 Kbits of embedded SRAM at up to
600 MHz operation. This chapter describes TriMatrix memory blocks,
modes, features, and design considerations.
