(a) Write the MIPS assembly language code to push the given registers onto the stack. The registers should be pushed onto the stack in the order that they are listed. St2, Sfp, $ra, $s1, $s3 (b) Draw the stack. Assume that the stack pointer is initialized to 0xFFFFFFFC. Show the contents of stack after all registers have been pushed onto it. Specify the address of each location of the stack used. Indicate the location of the stack pointer ($sp) after the registers have been pushed onto the stack. (c) Write the MIPS assembly language code to properly restore the value to each register.
