Cache performance model

Cache Performance Model

This project provides a model for simulating cache performance, including different cache configurations and replacement policies.

pip install cache-performance-model

Classes

Cache

Cache is an abstract base class for different cache models. It provides common functionality and properties for cache simulation.

DirectMappedCache

DirectMappedCache is a class for simulating a direct-mapped cache. It inherits from Cache and implements the read and write methods.

SetAssociativeCache

SetAssociativeCache is a class for simulating a set-associative cache. It inherits from Cache and implements the read and write methods. It supports different replacement policies such as RANDOM, FIFO, LRU, NMRU, and PLRU.

FullyAssociativeCache

FullyAssociativeCache is a class for simulating a fully associative cache. It inherits from Cache and implements the read and write methods. It supports different replacement policies such as RANDOM, FIFO, LRU, NMRU, and PLRU.

Examples

Direct Mapped Cache

from cache_performance_model.cache_model import DirectMappedCache

# Create a direct-mapped cache instance
cache = DirectMappedCache(cache_line_bytes=64, cache_size_kib=4)

# Perform read and write operations
cache.read(0x1A2B3C4D)
cache.write(0x1A2B3C4D)

# Print cache statistics
cache.stats()

Set Associative Cache

from cache_performance_model.cache_model import SetAssociativeCache
from cache_performance_model.types import ReplacementPolicy

# Create a set-associative cache instance with LRU replacement policy
cache = SetAssociativeCache(cache_line_bytes=64, cache_size_kib=4, n_way=4, replacement_policy=ReplacementPolicy.LRU)

# Perform read and write operations
cache.read(0x1A2B3C4D)
cache.write(0x1A2B3C4D)

# Print cache statistics
cache.stats()

Fully Associative Cache

from cache_performance_model.cache_model import FullyAssociativeCache
from cache_performance_model.types import ReplacementPolicy

# Create a fully associative cache instance with RANDOM replacement policy
cache = FullyAssociativeCache(cache_line_bytes=64, cache_size_kib=4, replacement_policy=ReplacementPolicy.RANDOM)

# Perform read and write operations
cache.read(0x1A2B3C4D)
cache.write(0x1A2B3C4D)

# Print cache statistics
cache.stats()
