WebSep 8, 2014 · The basic approach is (assuming shifting by 1) :-. Shift the top 16 bits. Set the bottom bit of the top 16 bits to the top bit of the bottom 16 bits. Shift the bottom 16 bits. Depends a bit on your hardware... but you could try :-. assuming unsigned long is 32 bits. assuming Big Endian. then :-. WebThe new multiply instructions are specifically designed to improve 16-bit multiplication. This chapter presents solutions for using the hardware multiplier to do multiplication with 16-bit operands. The figure below schematically illustrates the general algorithm for multiplying two 16-bit numbers with a 32-bit result (C = A • B). ...

Since you are using 17bits you need to be using 32bit mult. It's takes 1 cycle to do a 16bit x 16bit mult. To do a 32bit x 32bit takes 17 cycles which could yield a 64bit result. indian sweets images with name
