dont copy from any existing answer diretly for sure i will downvote dont post without knowledge
Generate MIPS code for the following code segments assuming that all variables are in memory locations. clear steps
dont post copied content posting multiple times dont answer if dont know
Answer by True or False and correct the False: 1- The instruction : MOV [Dx+SI], Ax is allowed T 2- The instruction : MOV ES:[SI], Ax is not allowedY 3- Translate (XLAT) converts the data in AL into a number stored at the memory location addressed by Bx plus AL. 4- DWORD PTR is used to address a 16-bit data of a number stored in memory F 5- REP is an instruction used to repeat any instruction as much as the value in Cx register.
