image text in transcribed

The following diagram shows stacks, variables, and code for two threads that switch via the yield 120 function. The code is written in CSx600 assembly language. sp1 and sp2 are the saved respective stack pointers for the two threads. Assumptions & Clarifications - All instructions and data are assumed to be 4 bytes - PUSH X is equivalent to (SP)=X (pre-decrement) - POP X is equivalent to X=(SP++) (post-increment) - CALL X is a single instruction equivalent to PUSH PC+4, JMP X - RET is equivalent to POP PC Starting with the stack pointer and program counter given above, the CPU will execute instructions until it reaches "---DONE---" with PC=0x508. Deliverable For each of the instructions, give the following information: 1. Instruction address, i.e., the value of the program counter [PC] 2. The instruction at that address, i.e., "MOV SP +EAX ") 3. Identify any registers or memory locations (give the specific addresses) that are modified by that instruction, and provide their new contents
