SS2 Execution Scheme

SS2 is a superscalar version of the Mips architecture designed by Pirouz Bazargan-Sabet. In the course unit 4I100, this architecture is studied throughout examples of assembly code execution inside the pipelines. For this, one needs to represent on a simplified scheme the execution of the instructions cycle by cycle inside the pipelines. This page implements the execution scheme for a given code.

Code

_strupper_loop: Lb r8, 0(r4) ; lire src[i] Slt r9, r8, r11 ; src[i] < 'a' Slt r10, r12, r8 ; 'z' < src[i] Or r10, r10, r9 ; et des 2 conditions Bne r10, r0, _strupper_endif ; si 1 des 2 cond vraie Nop Addiu r8, r8, 'A'-'a'; transformer en majuscule Sb r8, 0(r4) _strupper_endif: Addiu r4, r4, 1 ; caractère suivant Bne r8, r0, _strupper_loop Nop
