Assume the usage of stack machine that includes the operations PUSH, POP, ADD,SUB, MUL, DIV. Arithmetic operations will involve top two elements of stack (T-1) OP (T) =T where T is top of stack and (T-1) is the second element of stack. Identify the value in Register R1 after executing the following instructions in sequence: PUSH3, PUSH4, PUSH6, ADD, PUSH8, SUB, MUL, PUSH2, DIV, POPR1 3 8 O 10 Assume the usage of 2-bit dynamic branch prediction scheme where the change of prediction occurs only if it is predicted wrongly twice. Assume the predictions are T. T. NT, NT while actual outcomes of branches are NT,NT,NTT. What is the next prediction? T indicates "Taken' and NT indicates 'Not Taken'." O Taken O Not Taken O cannot determine Taken or Not taken
