New instruction will decrement a Variable stored in amemory location and store the decremented value in a register (Rt). Thisnew instruction will be called DECR.Its usage and interpretation isUsage:DECR Offset(4*Rs),RtInterpretation:Reg[Rt]= Mem[4*Rs+Offset] - 1Which blocks are used and which control signals are generated for thisinstruction. How would the Instruction code fields look like ? Do we needto add an extra hardware logic, explain ?(You may draw a simplified datapath flow)

Write the corresponding Mic-2 MAL and Mic-3 instructions to implement the following IJVM assembly instructions using a minimum number of clock cycles. 1. WORDPUSH word: Pushes an unsigned 2-byte operand to the top of the stack. 2. BLKLOAD count : Pushes a block of local variables onto the top of stack, starting with the first local variable. The number of variables for be pushed is specified by the 1-byte unsigned operand. 3. INEGATE : Pops a word from the stack and push the negated value. 4. IF_GE offset : Pop two words from stack and branch if the first popped word is greater than or equal to the second popped word.
We want to design a new K-format instruction for a branch-equal-immediate. A: What information would need to be encoded in a beq R2, 7, loop instruction? B: Why can't we have a beq R2, 7, loop instruction? and C: How could we fix this? Hint: think about the instruction encodings and what we need to encode such an instruction. A: beq R2, 7, loop needs to encode: B: Why can't we have this with the R/I/J formats? Name R-Format I-format J-format K-format C: What tradeoff could we make to implement a K-format?

A microprocessor has an increment memory direct instruction, which adds 1 to the value in a memory location. The instruction has five stages: fetch opcode(four bus clock cycles),fetch operand address (three cycles), fetch operand (three cycles) add 1 to operand (three cycles), and store operand (three cycles). a. By what amount (in percent) will the duration of the instruction increase if we have to insert two bus wait states in each memory read and memory write operation? b. repeat assuming that the increment operation takes 13 cycles instead of 3 cycles
answer with proper explanation and step by step solution. The instruction is to use a "loop" to write the MIPS code for this.
Orthogonality means that an instruction set has a "backup" instruction that can be used instead of any other instruction that does the same thing. It's up to you to prove or disprove what I think.
A certain ISA has a 32-bit word size, uses single word (32-bit) instructions, has 66 opcodes, 64 registers, and 1G of byte-addressable memory. One group of instructions in this ISA takes the form: OPCODE | DESTINATION REGISTER | SOURCE REG. | Flag | IMMEDIATE VALUE Or OPCODE | DESTINATION REGISTER | SOURCE REG. 1 | Flag | SOURCE REG. 2 A single bit in the instruction ("Flag") is used to differentiate these two addressing modes. Another group of instructions takes the form OPCODE | SOURCE/DESTINATION REGISTER | PC OFFSET Where PC Offset is the 2's complement "distance" from the current PC to the labelled location.
In some instruction sets, call and return instructions make use of a RR register to hold the return address rather than doing so on the stack. Show how the code in the above problem should be changed if call and return instructions used a RR register for return addresses rather than the stack. Don't change the program's function. 500 MOV R1, X 501 MOV R2, Y 502 MOV R3, Z 503 PUSH R1 504 CALL 550 505 POP R3 506 CALL 560 507 HALT · · 550 PUSH R2 551 CALL 560 552 POP R2 553 RET · · 560 PUSH R3 561 PUSH R1 562 POP R2 563 POP R1 564 RET
