- Most Intel CPUs use the __________, in which each memory address is represented by two integers.A digital computer has a memory unit with 24 bits per word. The instruction set consists of 150 different operations. All instructions have an operation code part (opcode) and an address part (allowing for only one address). Each instruction is stored in one word ofmemory.a. How many bits are needed for the opcode?b. How many bits are left for the address part of the instruction?c. What is the maximum allowable size for memory?d. What is the largest unsigned binary number that can be accommodated in one word of memory?Q6: A digital computer has a memory unit with 24 bits per word. The instruction set consists of 110 different operations. All instructions have an operation code part (opcode) and an address part (allowing for only one address). Each instruction is stored in one word of memory. (a) How many bits are needed for the opcode? (b) How many bits are left for the address part of the instruction? (c) What is the maximum allowable size for memory? (d) Can we extend this instruction set by adding new 10 instructions and keeping the same length of opcode part? (e) Determine the type of this instruction set: stack-based ISA or accumulator- based ISA or general purpose registers-based ISA?
- The use of transistors in the construction of RAM and ROM leads me to believe that there is no need for cache memory.The term "temporary storage" may also be thought of as "random access memory" (RAM) that is momentarily vacant. Imagine a machine that only had one kind of memory—is it even possible?Suppose the RAM for a certain computer has 256M words, where each word is 16 bits long. a. What is the capacity of this memory expressed in bytes? b. If this RAM is byte addressable, how many bits must an address contain? c. If this RAM is word addressable, how many bits must an address contain?Suppose that the CPU is tasked to read data "X" from RAM with an address "C7FFF" and write the same data to RAM with an address "C8FFF" to replace data "Y." Describe in your own words how data X overwrites Y in RAM.
- Question 6 Suppose you have a RISC machine with a 1.6 GHz clock (i.e., the clock ticks 1.6 billion times per second). This particular computer uses an instruction cache, a data cache, an operand fetch unit, and an operand store unit. The instruction set includes simple instructions with the following timings: set reg, immed 2 clock cycle 2 clock cycles 2 clock cycle 4 clock cycles 3 clock cycles loop label add reg, immed add reg, reg load reg, mem Assume that the following code franent is used to sum the element of a numeric array. If the initialization code has already executed (i.e. the SET instructions have already finished execution) how many array elements can be processed in 5 ms? Round your answer to the nearest integer. Recall that 1 ms = 0.001 seconds. Also assume that there are no physical memory limitations, implying that the array can be as large as desired. ri, e r2, MAX_SIZE ;initialize loop counter r3, @list initialize sum set set set initialize array pointer more: load…8086Microprocessor 1.
