FIFO RAM Blocks
The option to select 2 FIFO RAM blocks depends on the parameters you select on the
Basic Parameters tab. These parameters affect the FIFO buffer size and FIFO buffer
width, both of which play a role in memory utilization.
When you select 2 FIFO RAM blocks , the timing performance of the MegaCore
function may decrease (because the memory rdata bus is unregistered, as opposed to
registered for 4 FIFO RAM blocks ). Altera recommends that you do full compilations
for both configurations before deciding which one to choose.
1
Use 2 FIFO RAM block only if it gives an improvement in memory utilization and if
your timing requirements are still met.
Table 3–3 shows the support for the 2 FIFO RAM block . 4 FIFO RAM block supports
all configuration.
