- a. In what way are general-purpose registers and main memory cells similar?
- b. In what way do general-purpose registers and main memory cells differ?
a.
General-Purpose Registers:
General-Purpose registers are used to store the temporary data or memory location address. It holds the data for some time, but it does not store the data permanently. It holds the address or data till the next instruction is being executed.
Main memory:
Main memory is that physical memory where data and programs are stored when they are also being used by the processor. All the data and executed programs are copied from a storage device into main memory by the computer.
Explanation of Solution
Similarity between general-purpose registers and main memory:
General-Purpose registers are basically used to store the data and addresses. It holds the data for short duration.
Similarly, data is stored in main memory cells. The main memory is also used as storage device.
b.
General-Purpose Registers:
General-Purpose registers are used to store the temporary data or memory location address. It holds the data for some time, but it does not store the data permanently. It holds the address or data till the next instruction is being executed.
Main memory:
Main memory is that physical memory where data and programs are stored when they are also being used by the processor. All the data and executed programs are copied from a storage device into main memory by the computer.
Explanation of Solution
Difference between general-purpose registers and main memory:
General purpose register | Main memory |
These registers hold the data till the next instruction is being executed. | Main memory stores the data and instruction that is required in CPU for currently executing programs. |
It is used for temporary storage device. | It is used for permanent storage of data in the device. |
Register can hold data of 32-bits to 64-bits. | Main memory can store large amount of data from GB to TB. |

- Most Intel CPUs use the __________, in which each memory address is represented by two integers.arrow_forwardAnswer T (True) or F (False) for the following questions 1. Computers using word addressable memories have more memory than computers using byte addressable memory 2.3-operand ISA has higher performance than 1-operand ISA 3. It is common for ISAS to have special instructions to deal with data types of different lengthsarrow_forwardb. How many bits are required to address a 4M × 16 main memory if main memory is byte-addressable?c. How many bits are required to address a 1M × 8 main memory if main memory is byte-addressable?arrow_forward
- Choose the incorrect statement of the microprocessor buses. A. Data bus and control bus are bidirectional buses in microprocessor. B. Data bus transfer data to or from central processing unit. C. A control bus manages activities inside the microprocessor. D. Address bus transfers address and data from registers to the memory and vice versa. E. The size of the microprocessor is not determined by the size of the adress busarrow_forwardChoose the correct answer: Opcode, funct3 and funct7/6 in instruction format are used to identify the: ● (a) function. (b) instruction. (c) branch. (d) memory address. The register that hold the address of the current instruction being executed is called: (a) saved register. (b) global pointer. (e) stack pointer. (d) program counter. Placing the executable file into the memory for execution by the processor is the role of: (a) assembler. (b) linker. (e) loader. (d) compiler. ● The part which responsible for transmitting the data to/from the processor is: (a) control unit. (b) Datapath. (c) data bus. (d) memory. ● ● Parallel hardware cannot be used for faster division because: (a) subtraction is conditional on sign of remainder. (b) multiplication is conditional on sign of remainder. (c) subtraction is conditional on sign of divisor. (d) multiplication is conditional on sign of divisor. ● we cannot slower the clock cycle t fit the floating-point adder algorithm into one clock cycle…arrow_forwardMatch the following components with their respective functionalities: A. A device that Is incremented by 1 modulo the capacity of the register on every clock cycle is known as B.A small data holding place within the CPU is called C. A device that can be used to store one bit is called D. A device that uses upper address lines as inputs in order to enable a specific RAM chip for data exchange with the CPU is cailed E. A device that performs arithmetic and logical operations on data is called F. A device that changes ones to zeros and zeros to ones in a binary number is called select ♥ 1. a D flip flop select 2. a counter select 3. a decoder select 4. a complementer select 5. an ALU select 6. a registerarrow_forward
- Choose the right answer from among the following statements. 1) According to the 80/20 rule, 80 percent of the instructions are performed and only 20 percent of the instructions are generated. 2) The external bus in the von Neumann architecture is only for the purpose of data memory storage.arrow_forwardExplain briefly the four methods now in use to connect the CPU and the main memory.arrow_forwardThe following is an 8051 instruction:CJNE A,#'Q',AHEADa. What is the opcode for this instruction?b. How many bytes long is this instruction?c. Explain the purpose of each byte of this instruction.d. How many machine cycles are required to execute this instruction?e. If an 8051 is operating from a 10 MHz crystal, how long does this instructiontake to execute?arrow_forward
- Indicate whether each of the following statements is true or false and justify your answer with reasoning and supportive or counter examples: (a) The CPU computations and I/O operations cannot be overlapped in a multipro- grammed computer. (b) Synchronization of all PEs in an SIMD computer is done by hardware rather than by software as is often done in most MIMD computers. (c) As far as programmability is concerned, shared-memory multiprocessors offer sim- pler interprocessor communication support than that offered by a message-passing multicomputer.arrow_forwardQuestion 2: What are flag registers? Name all 14 registers. Why they are necessary in assembly language? Use block diagram to explain all registers in detail with examples for each register.arrow_forwardQ: The contract between hardware and software is known as Instruction set architecture. Explain the working of registers with two main process of Von-Neuman architecture and highlight ISA in this working.arrow_forward
