G06F 12/0802

Addressing of a memory level in which the access to the desired data or data block requires associative addressing means, e.g. caches

Introduced: January 2016

Full Title

Full titles differ between systems:

IPC:

Accessing, addressing or allocating within memory systems or architectures > Addressing or allocation; Relocation > in hierarchically structured memory systems, e.g. virtual memory systems > Addressing of a memory level in which the access to the desired data or data block requires associative addressing means, e.g. caches

CPC:

Accessing, addressing or allocating within memory systems or architectures (digital input from, or digital output to record carriers, e.g. to disk storage units, G06F3/06) > Addressing or allocation; Relocation (program address sequencing G06F9/00; arrangements for selecting an address in a digital store G11C8/00) > in hierarchically structured memory systems, e.g. virtual memory systems > Addressing of a memory level in which the access to the desired data or data block requires associative addressing means, e.g. caches

IPC and CPC are identically structured here. All 11 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.
