Using an expanding opcode encoding for instructions, is it possible to...

4 bits are for the opcode so number of 2 address instructions will be 2⁴ =16 ---so 14 double instructions are possible
But out of 16 only 14 are used so 2 are still left which can be used for 1 address instruction
For 1 address instruction we can use not only the 2 left over but also the 6 bits of operand1(to make it one address)--- so
6 bits that is 64 so they are laready 2 which each contains 64 so total 128 single address instructions -----so 127 single
instructions are possible
But out of 128 ,127 are used so 1 left which can be used for zero address instruction to make number of zero address we
can use the operand2 address 6 bits so total possible are 64 so total 1*64 = 64 zero address instructions are possible
So all encoding are possible

Suppose a stack implementation supports an instruction REVERSE, which reverses the order of elements on the stack, in addition to the PUSH and POP instructions. Which one of the following statements is TRUE (with respect to this modified stack)?

View answer

An instruction pipeline has five stages, namely, instruction fetch (IF), instruction decode and register fetch (ID/RF), instruction execution (EX), memory access (MEM), and register writeback (WB) with stage latencies 1 ns, 2.2 ns, 2 ns, 1 ns, and 0.75 ns, respectively (ns stands for nanoseconds). To gain in terms of frequency, the designers have decided to split theID/RF stage into three stages (ID, RF1, RF2) each of latency 2.2/3 ns. Also, the EX stage is split into two stages (EX1, EX2) each of latency 1 ns. The new design has a total of eight pipeline stages. A program has 20% branch instructions which execute in the EX stage and produce the next instruction pointer at the end of the EX stage in the old design and at the end of the EX2 stage in the new design. The IF stage stalls after fetching a branch instruction until the next instruction pointer is computed. All instructions other than the branch instruction have an average CPI of one in both the designs. The execution times of this program on the old and the new design are P and Q nanoseconds, respectively. The value of P/Q is __________. Correct answer is '1.54'. Can you explain this answer?
