$2.(30$ pts$)$ In a hyperthetic asembly code depicted below, a jump instruction $($at loca tion with the addres lable $$ABC$)$ uses the PC$-$relative addressing mode to jump to the load instruction with the address label $$HERE$($note: this jump is a backward jump$)$: : : HERE ABC load r$1,64($r$2)$ : : jump HERE$($PC$)$ : Assume that after the first pass of assembly process, the label $$ABC$$ is determined to have an address value of x$4$c$14$ and the label $$HERE$$ has x$4$bd$0.$ Answer each of the following questions. $($a$)$ In the second pass of assembly process to assemble the code for the jump instruction, show how the assembler determines the reltaive distance value $($a $16-$bit value$)$ to be placed in the machine code, and the value thus calculated. Determine its decimal value $($note: should be a negative value due to jump back$),$ and determine how many instructions backward this $$jump$$ instruction is to jump in order to reach the $$load$$ instruction.. $($b$)$ Assume that the code is relocated to another secion of memory after a context switch, and the jump instruction is now at x$6800,$ answer each of the following questions. i$.$ What should be the address of the load instruction now? ii$.$ Show how the CPU calculates this correct target location when this jump instruction is executed, using the machine code derived from $($a$).$
