Question: A computer system has the following parameters: - Cache access time of 25ns - Memory access time of 44 ns - Write I/O Miss rate
A computer system has the following parameters:
- Cache access time of 25ns
- Memory access time of 44 ns
- Write I/O Miss rate of 20%
- Read I/O Hit rate is 100%
- Disk rotating at 5000 revolutions per second with an average seek time of around 4 microseconds and an average of 200 sectors per track
- As always, you can assume that there are 1024 bytes per sector
If there are a total of 1020 instructions in a program equally split up between read and write I/O operations in this set of instructions, and assuming that there is no required data in main memory, calculate the total time taken for this program to execute in this system.
