WebNov 29, 2012 · An on-chip RAM has a read bus which can only access one word in the memory, and changes on a clock edge. So builds the memory instead out of a bunch of LUTs. In that case, you can think of the memory as build from a 2D array of flip-flops, and now it can wire up to all the words.

A read may occur from a previously selected queue by taking the REN input LOW. Note, here that a new word is accessed on the rising edge of read clock and is available for the reading device to process that word on the following rising edge of read clock. 2.

WebFeb 7, 2013 · Basically the D_out is valid when empty /= '1', and so read_en acts more like an ACK rather than an enable. In a normal fifo you have to assert read_en to get the d_word on the next clock. FWFT/look ahead have a combinatorial output rather than a registered output, so timing usually results in a lower fmax. the pro's/cons will depend on whether ... WebA FWFT FIFO presents the data on the output as soon as it's available, so a low @empty signal means that the data on the output is valid. The meaning of @rd_en is different as well: For a "standard FIFO" it means "bring me data". On a FWFT FIFO it's something like "I just used the data, bring me the next data if you have it".
