CPU control unit has the following phases of operations: Fetch phase, Decode phase, and Execute phase. The following pseudo-code demonstrates these three phases. Please add more pseudo-codes to implement the following two functions: a) CPU handles Interrupt to enable Interrupt-driven I/O operations; b) CPU solves race conditions

*** Answer in pseudo-code for C language ***

PC = ;

IR = memory[PC];

haltFlag = CLEAR;

while(haltFlag not SET) {

execute(IR);

PC = PC + sizeof(INSTRUCT);

IR = memory[PC]; // fetch phase

/* Please add your pseudo-code in the following */

};
