Select where the source operands are located for the following two LC-3 instructions:0001 111 010 0 00 0111010 010 110011110If the source operands are located in memory, also distinguish the addressing mode used to access that memory.  from memory using Base+Offset adressing mode   immediately from the instruction's address Correct!  directly from a register Correct Answer  from memory using Indirect addressing mode You Answered  from memory using PC-Relative addressing mode   immediately from the instruction

Registers X1, X2, X3 have corresponding data stored in each location: X1: AX2: BX3: C Which set of ARM instructions will accomplish A=B+C?

Show the contents in hexadecimal of registers PC, AR, DR, IR, and SC of thebasic computer when an ISZ indirect instruction is fetched from memory andexecuted. The initial content of PC is 7FF. The content of memory at address7FF is EA9F. The content of memory at address A9F is 0C35. The content ofmemory at address C35 is FFFF. Give the answer in a table with five columns,one for each register and a row for each timing signal. Show the contents of theregisters after the positive transition of each clock pulse.170 CHAPTER FIVE Basic Computer Organization and Design
