Cache memory simulator

This program simulates how cache memory works and interacts with the processor and main memory of a computer.

Instructions

Running the program

Open a terminal in the main directory, type make and press Enter.

Component parameters

Lines 16 through 18 of main.py contain the constructors for the components to be simulated. There, you can change RAM memory and block size, cache memory and line size, and CPU replacement algorithm (lfu or random). At line 20, you may change the quantity of random accesses generated and sent to the CPU.

Manual memory accesses

Instead of random accesses using the random_access function, you may opt to manually issue commands to the CPU.

• cpu.read(addr: int)

Retrieves the word located at address addr of main memory. Inserting this method in a print call prints the word to the terminal.

• cpu.read_modify(new_data: int, addr: int)

Retrieves the word located at address addr of main memory. Inserting this method in a print call prints the word to the terminal. After reading the word from memory, this function also overwrites new_data to address addr of main memory.
