Table 10–4
Stratix and Stratix GX TriMatrix memory blocks only support pipelined
mode, while APEX II and APEX 20K ESBs support both pipelined and
flow-through modes. Since all TriMatrix memory blocks can be
pipelined, all input data and address lines are registered, while outputs
can be either registered or combinatorial. You can use Stratix and
Stratix GX memory block registers to implement input and output
registers without utilizing additional resources. You can compile designs
containing pipelined memory blocks (inputs registered) for Stratix and
Stratix GX devices without any modifications. However, if an APEX II or
