RISC machines than in superscalar processuIS. (c) Show the pipeline activity for the following code fragment with a...
2. (a) Briefly describe the compiler-based register optimization technique (typically (4 marks) (b) Describe the delayed branch technique and explain why it is more common in (4 marks) tetch, indirect and moon used for RISC machines). (c) Show the pipeline activity for the following code fragment with and without applying the delayed branch technique. Assume that there are three pipeline stages (fetch-decode, address calculation, data movement) for load and store RISC machines than in superscalar processors. instructions and two stages...
a) Describe the main techniques used by superscalar processors to achieve a high degree of machine-level parallelism. Consider the following assembly code: I1: LOAD r3 (r1) TO 12: MOVE r4 #1 13: ADD r3 r3 r4 I4: LOAD r2 (r2) 15: MOVE r4 #2 I6: MUL r2 r2 r4 17: MUL r3 r3 r2 I8: LOAD r4 (r1) 19: MOVE r1 #3 I10: ADD r4 r4 r1 I11: MUL r3 r3 r4 Using register renaming reorganise the code from 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: LoadZero X – this is...

For questions 3-4, provide the full MARIE RTN (register transfer notation) for these new MARIE operations. 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 in your RTN. 3) AutoIncrLoad X - the autoincrement addressing mode is used to access a...
