Sign extend in mips
WebSign extension • Internally the ALU (adder) deals with 32-bit numbers • What happens to the 16-bit constant? – Extended to 32 bits • If the Opcode says “unsigned” (e.g., addiu) – Fill upper 16 bits with 0’s • If the Opcode says “signed” (e.g., addi) – Fill upper 16 bits with the msb of the 16 bit constant WebFor two's complement representation, the extension consists of replicating the sign, as shown for m = 5 in Figure 3.1. To simplify the description that follows, we place the binary point after the “sign” bit and index as for fractions. That is, the operands are in the range −1 ≤ x ≤ 1 − 2 −n, and the two'ss complement ...

Sign extension can affect only numbers from 0x80000000 through 0xFFFFFFFF. That is, sign extension affects only numbers that can be written in 32 bits with the high bit equal to 1. The number 0x12345678 always remains …
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). WebMIPS uses a 32-bit fixed-length instruction format. There are only three different instruction word formats: Register format ... sign-extend, and place result in Rt.
