How many bits are in an instruction?
32-bit
6.4. 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 required to implement a microprocessor having 115 instruction?
7 bits
So the number of bits required to implement a microprocessor having 115 instructions is 7 bits.
How many address bits would you need to read the contents of memory containing 2000 words?
With regard to memory, 2k usually means 2*(2^10) — that is, 2048. Now, depending on context, that may be 2048 bits, 2048 bytes ( 8*2048 bits), or 2048 words — (word-size-in-bits) * 2048 bits.
How many bits are in a single byte?
eight bits
A byte consists of 8 adjacent binary digits (bits), each of which consists of a 0 or 1. (Originally, a byte was any string of more than one bit that made up a simple piece of information like a single character. Thus, for example, there were four- or six-bit bytes, but eventually the standard settled on eight bits.)
How many bits are required to encode each instruction in the set?
Solution: Each instruction has 5 distinct fields: Opcode, Register1, Register2, Register3, 12-bit immediate value Total instructions = 12; hence it requires 4 bits Total registers = 64; hence 6 bits are required to specify the register.
How many bits are required to address 128mb of memory?
227
How many bits are needed to address any single word in memory? The memory address space is 128 MB, which means 227. However, each word is 8 (23) bytes, which means that you have 224 words. This means you need log2 224 or 24 bits, to address each word.
How many address bits are required to represent 32K memory?
2e10 = 1024, so you need 10 bits to address every byte in a kilobyte. Likewise, you need 20 bits to address every byte in a megabyte, and 30 bits to address every byte in a gigabyte. 2e32 = 4294967296, which is the number of bytes in 4 gigabytes, so you need a 32 bit address for 4 GB of memory.
How many bits is 255?
8 bits
How Many Bits Does 255 in Binary Have? We can count the number of zeros and ones to see how many bits are used to represent 255 in binary i.e. 11111111. Therefore, we have used 8 bits to represent 255 in binary.
How do you calculate the size of a program counter?
The program counter is simply the location of the instruction being executed, and so it will change based on the processor architecture. That is, a 64 bit architecture will need 64 bits to hold the program counter, a 32 bit will need 32, and so on.
