What else can I help you with?
What is a memory performance?
it is defined by access time and cycle time
What is memory access time?
The time required by a processor to access data or to write data from and to memory chip is referred as access time.
What is the Memory access time?
The time required by a processor to access data or to write data from and to memory chip is referred as access time.
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
Cache memory enhances?
memory access time.
Which memory has the shortest access time?
cache memory
How do you calculate memory access time?
Memory access time can be calculated using the formula: Memory Access Time = Hit Time + (Miss Rate × Miss Penalty). Here, the hit time is the time taken to access data from cache when it is found, while the miss rate is the frequency of cache misses. The miss penalty is the time required to retrieve data from the main memory when it is not available in the cache. By combining these factors, you can estimate the overall memory access time.
What is the formula to calculate the average memory access time in a computer system?
The formula to calculate the average memory access time in a computer system is: Average Memory Access Time Hit Time Miss Rate x Miss Penalty
How does the access time of storage compare with the access time of memory?
access times from memory is 200,000 times faster than access times from storage devices due to the mechanical movement involved.
What is the measure of memory devices operating speed called?
Memory device operating speed is measured in cycle time which is the amount of time required for memory to perform read and write operation and return to its original state ready for next operaiton. Access time is another measure of memory speed which is only the time required for read operation or it is the time between data receiving (read operation) and the data becoming available at the memory output.
Why register to register instruction is faster?
Register to register addressing mode is faster because you don't have to do an extra memory access cycle or more.Register to register addressing mode is faster because:Registers are part of and are directly accessibility by the CPU assembly.They electronics that make up a register use more expensive but faster circuitry.Since it does not require memory access, the steps and time involved in memory address decoding and memory access are skipped.
Is access time of memory is slow compared with the access time of storage?
access times from memory is 200,000 times faster than access times from storage devices due to the mechanical movement involved.
