Subroutines in MIPS Determines the minimum of two integers Functions within the MIPS slides describe how one can use subroutines (also called procedures, functions, and methods) in MIPS. Because of the importance of subroutines in modern programming, most hardware designers include mechanisms to help programmers. In a high-level language like C or Java, most of the details of subroutine calling are hidden from the programmer. MIPS has special registers to send information to and from a subroutine. The registers $a0,...
im trying to complete mips program code about a calculator program that can calculate integer addition / subtraction written using the MIPS assembler. im having hard times to debug this. The input is given to the array of Formula char (base address $ s0) in the form of a formula. The null character (\ 0, ASCII code 0) is placed at the end. The calculation result is given to the register $ s1 and the overflow is ignored. For example,...
