Hello, I am looking for a simple glue logic solution that has about 4k D-flip flops. The glue logic just involve simple counters, shift registers, and combination logic. But I need very tigh...

Basically it is very simple, it has a 48 x 32 D-type flip flops, there are 48 data lines going into the flip flops inputs, and the flip flops are clocked serially to form a buffer that is 32 deep by 48 width. Once I receive a logic signal, it disable data loading and freeze the data inside these flip flops. Then the logic should load the D flip flops in each line into a shift register, so there should be 32 shift registers with a length of 48. Then I can slowly shift the data out from the shift registers to other IO pins. So this is the most critical part which require as high a speed as possible. The target clock speed for this block is 100MHz. I am hoping the EP4CE6 can do the job. Thanks! BR - Henry --- Quote End --- Hi Henry, in Quartus you have a megawizard which offers some Ip blocks. Have a look to http://www.altera.com/literature/ug/ug_shift_register_ram_based.pdf Kind regards GPK
