How and when should memory swap happen? how about if I have a jump or a load from an address which is not within the Sram, how to I take it from Flash and should I take it from flash directly or should I use DMA to put it in Sram and than to work with it? and how do I implement these.
Help please?
Yes but how do I compose the big number after I do this, how do I shift add move carry and then add the carry again?(if is signed number than only when it comes to check the up half the sign matters the down half can be just multiplier)
Can you give some short tips, what with what to mul and to add and how to play with the carrys and how to make it for signed too(just some algorithmical hints) please?
The multiplication algorithm that I used does not matter it just have to finish the operation in 10ns, the method I posed above I saw in same cores from ETHZ and they said that this method is a single cycle although I have my doubts because I think they are doing something like:
Mul something...
I am looking for 100 Mhz multiplier in a single cycle area is not a problem(180nm ON-semi), (I tried sequential and booth).
I knew a method but I am not sure if it will reach that speed is the old method from 3rd grade:
P = multiplicand[31:16]
Q = multiplicand[15:0]
R = multiplier [31:16]
S =...
