Write a sequence of MIPS instructions to find the absolute value of the value in register $s0 and store it into register $t0. Assume you do not have access to multiplication instructions. Use as few instructions as possible. You do not have to assemble your code for this question, but you may do so to validate that it works.

You can find the detailed description of the instructions for S12 in the reference manual “S12CPUV2.pdf". This document is available in the lab. 1. Example: The following program (1) clear register A, then (2) add 3 to A ten times. It uses the zero flag and BNE with DECB ; this program adds value 3 to register A ten times ; A=0 COUNT EQU 10 ; use 10 for counter LDAB #COUNT ; load the counter CLRA AGAIN ADDA #3...

The AVR provides a rich instruction set to support high-level languages. The AVR address- ing modes also simplify the access of complex data structures. The AVR has a version of the ADD instruction that includes the C flag as one of the source operands, which enables multiple- precision addition operation. The AVR also has a version of the SUB instruction that includes the C flag as one of source operands and hence is used to perform multiprecision subtraction operation. The...

MARIE Assembly Code Problem For the following problem, please create new MARIE instructions by providing the full MARIE RTN (register transfer notation) for the described operation. Your answer should include the fetch, decode, operand fetch (if necessary), execution and store result (if necessary) stages. When you see X in these instructions, this is a main memory address (the last 12 bits of the 16-bit instruction) – refer to this as IR[11..0] and not X. Problem: ClearIndirect X – X is...
