Shift (sal shl sar shr) (IA-32 Assembly Language. A shift left logical instruction in mips assembly is used for shifting the bits to the left. the amount of shift depends on the value we give it. when we perform a shift left logical instruction the low bits at right most is replaced by zeros and the high right most bit is discarded. (number of discarded bits depend on the amount of shift), outline 2.1 assembly language program structure 2.2 arithmetic instructions 2.3 branch and loop instructions 2.4 shift and rotate instructions.

Mips-i assembly language instruction set. instruction set (integer instructions only) shift the contents of register rsrc1 left (right) arithmetic shift instructions . in an arithmetic shift (also referred to as signed shift), like a logical shift, the bits that slide off the end disappear (except for the last, which goes into the carry flag). but in an arithmetic shift, the spaces are filled in such a way to preserve the sign of the number being slid.

Zwhen there are two operands, both operands must have the same size (except shift and rotate instructions). for example: al, dl dx, ax m1 db ? al, m1 m2 dw ? shift and rotate instructions computer organization and assembly language – nuces hina anwar – slide 3 logical vs arithmetic shifts a logical shift fills the
