Web--- Notes: The sign-extension logic modeled by BFD is an integral part of the MIPS64 architecture spec. It appears in the virtual address map, where sign extension allows for 32-bit compatibility segments [1] with 64-bit addressing. 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).

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.

WebWithout the patch below, only 32 bits are being transferred, thus leaving in place the (high 32-bit) sign extension of -1. When the sim attempts to execute the instruction noted above, it first checks to make sure that the sign extension for the register being transferred is sane. It is not, and therefore quits printing the UNPREDICTABLE message. WebEmail address Password Log in. Have you forgotten your password? Communities & Collections. All of DSpace.
