What is bus cycle in a microprocessor?
Bus cycle is a single transaction between the main memory and the CPU.
Explain instruction cycle?
An instruction cycle is the rudimentary operation cycle of any computer. It involves the CPU fetching a program from memory and executing it fully.
Instruction cycle with indirect?
In an instruction cycle with indirect addressing, the CPU fetches the instruction, decodes it to determine the memory address of the operand stored in a register, fetches the operand from the memory location pointed to by the register, and executes the instruction using the operand. Finally, the CPU stores the result back in memory if needed. This extra step of fetching the operand based on the indirect memory address adds complexity to the instruction cycle.
Why does memory access take more machine cycle than register access?
Because of different in speeds of cpu the system bus and the memory circut
When evaluating CPU memory do you check the cache memory?
The only memory on the CPU is cache memory and it is only dependent on the CPU type and generation you use.
What is the definition of fetch cycle?
Fetch cycle is defined as a part of instruction cycle in which data is fetched from the memory pointed by Holds the address of a memory block to be read from or written to) and stores the data in MDR( a two-way register that holds data fetched from memory (and ready for the CPU to process) or data waiting to be stored in memory) for further processing. Instruction cycle= Fetch cycle+ Execute cycle
What does EDO stand for regarding RAM?
(Extended Data-Out) - A DRAM technology that shortens the read cycle between memory and CPU. On computers that support it, EDO memory allows a CPU to access memory 10 to 20 percent faster than comparable fast-page mode memory. Source: studynotes.net
What is a cycling machine?
Each time the CPU executes an instruction, it takes a series of steps. The complete series of steps is called a machine cycle. A machine cycle can be divided into two smaller cycles. These are instruction cycle and execution cycle. Instruction cycle: In instruction cycle CPU takes two steps-- 1. Fetching: Before the CPU can execute an instruction, the control unit must retrieve or fetch a command or data from the computer's memory. 2. Decoding: Before a command can be executed, the control unit must decode the command into instruction set. Execution cycle: In execution cycle CPU also takes two steps-- 1. Executing: When the command is executed, the CPU carried out the instructions in order by converting them into macrocode. 2. Storing: The CPU may be required to store the result of an instruction in memory.
Is CPU directly addressable by the memory?
Yes, the CPU is directly addressable by the memory.
Where is CPU and memory are located?
output device No The CPU and memory are located on the motherboard
Is the CPU updating cycle another name for the CPU processing cycle?
true
What is cycle stealing technique?
Cycle stealing is a technique used in accessing a computer's RAM without having to pass through the CPU. It is similar to direct memory access or DMA.
