from big picture (Architecture) to actual unit design (Mircro Architecture) , will not cover Circuit accumulator = adding number (need to hold a number) , adder doesn't need to hold statethis takes O(N) to compute dot product of length n vectors. e.g) 8 cycles if n is 8 usping multiple multiplier will be faster but how to merge the results ,need adder treenow it takes 2 cycle to calculate 8 len..
