- Some computers have an instruction that atomically exchanges the values of two memorylocations. It is defined as follows:Exchange(int var1, int var2):⟨ int temp; temp = var1; var1 = var2; var2 = temp; ⟩Above, temp is an internal machine register.Using Exchange, dev elop a solution to the critical section problem.

- Write programs that will accomplish the desired tasks listed below, using as few lines of code as possible.Use only opcodes that have been covered in class. Comment on each line of code. u) Store register A at the internal RAM location address in register Av) Copy program bytes 0100h to 0102h to internal RAM locations 20h to 22hw) Copy the data on the pins of port p2 to the port 2 latchx) PUSH the contents of the B register to TMODy) Copy the contents of external code memory address 0040h to IEz) Show a set of XCH instructions executes faster than PUSH and POP when saving the contents ofthe A register.The following processor status flags are shown by DumpRegs: Which processor status flags are visible?The class I'm taking is assembly programming. ***My compiler is visual studio. x86 on windows. must use masm.*** I am completely stuck.
