microprobe.target.uarch.cache.SetAssociativeCache

class SetAssociativeCache(element: MicroarchitectureElement, size: int, level: int, line_size: int, address_size: int, data: bool, ins: bool, ways: int)

Bases: Cache

Class to represent a set-associative cache.

__init__(element: MicroarchitectureElement, size: int, level: int, line_size: int, address_size: int, data: bool, ins: bool, ways: int)

Create a SetAssociativeCache object.

Parameters:

• element (MicroarchitectureElement) – Micrarchitecture element

• size (int) – Cache size in kilobytes

• level (int) – Cache level

• line_size (int) – Line size in bytes

• address_size (int) – Address size in bits

• data (bool) – Data cache flag

• ins (int) – Instruction cache flag

• ins – Cache ways

Returns:

Cache instance

Return type:

Cache
