What I am trying to do here is extend the address part of the instruction. For example, for Load store instruction if we extend the address part, the last bit is 20 and for conditional branch instruction, the last bit is 23.

WebMar 21, 2024 · 5.1: The Sign Extend Unit. The immediate values which can be part of an instruction are 8 bits, and can be used as an input to the ALU. However, the ALU accepts inputs which are 16 bits. Therefore, immediate values which are passed to the CPU must be expanded to fill 16 bits. The question is how to fill in the high 8 bits when expanding ...

WebNote that the cwd (convert word to double word) instruction does not sign extend the word in AX to the double word in EAX. Instead, it stores the H.O. word of the sign extension into the DX register (the notation "DX:AX" tells you that you have a double word value with DX containing the upper 16 bits and AX containing the lower 16 bits of the value). WebThe MIPS architecture insures this interoperability by defining that 32- bit operations will sign extend their results to fill 64- bit registers. Thus, using a 2's complement numeric representation, the , directly implements various 64bit operations (such as arithmetic operations) as single cycle operations , a single cycle ; that is, the cache data path is 64 …
