How many bits would you need to represent registers in machine code?
b) What can be the maximum number of bits that can represent the OPCODE? To find this, we have to find the number of bits that are used for the registers. Since there are 64 registers → 6 bits are needed (ceil(log264) = 6 bits) for each register.
How many total bits is a machine instruction?
6 The Power of the Stored Program. A program written in machine language is a series of 32-bit numbers representing the instructions. Like other binary numbers, these instructions can be stored in memory.
How many bits are there in the operation code?
How many bits are there in operation code, the register code part and the address part ? OP-code 32 – 1 – 18 – 6 bits = 7 bits.
How many bits are there in the operation code register code part and address part?
(a) Address: 18 bits Register code: 6 bits Indirect bit: 1 bit 32 – 25 = 7 bits for opcode.
How are address bits calculated?
Step 1: calculate the length of the address in bits (n bits) Step 2: calculate the number of memory locations 2^n(bits) Step 3: take the number of memory locations and multiply it by the Byte size of the memory cells.
How many total bits will an address in our system need to be?
Therefore 32 bits are required to uniquely address each 32-bit word. Therefore 34 bits are required to uniquely address each byte.
How many bits are there in address part?
32 bits
How many bits are needed to address each register?
The instruction consists of opcode and operands. Given the instruction set of size 12, 4 bits are required for opcode (2^4 = 16). As there are total 64 registers, 6 bits are required for identifying a register.
How many bits is a 32 register?
Therefore, we need at least 4 bits to represent 11 values. First you need to know how many general-purpose registers MIPS has. There are only 32 GP registers, numbered from $0 through $31. Hence, we need 5 bits to represent those registers (remember 2^5 = 32! ).
How many bits are in a signed 64 bit register?
Registers. x64 extends x86’s 8 general-purpose registers to be 64-bit, and adds 8 new 64-bit registers. The 64-bit registers have names beginning with “r”, so for example the 64-bit extension of eax is called rax.
Which register is a general purpose register?
The general purpose registers are used to store temporary data in the time of different operations in microprocessor. 8086 has eight general purpose registers. This is the accumulator. It is 16-bit registers, but it is divided into two 8-bit registers.
