Interconnection of, or transfer of information or other signals between, memories, input/output devices or central processing units (interface circuits for specific input/output devices G06F3/00 ; multiprocessor systems G06F15/16 )

Introduced: September 1968

Title

Titles differ between systems:

IPC: Interconnection of, or transfer of information or other signals between, memories, input/output devices or central processing units

CPC: Interconnection of, or transfer of information or other signals between, memories, input/output devices or central processing units (interface circuits for specific input/output devices G06F3/00 ; multiprocessor systems G06F15/16 )

Full Title

Full titles differ between systems:

IPC:

Interconnection of, or transfer of information or other signals between, memories, input/output devices or central processing units

CPC:

Interconnection of, or transfer of information or other signals between, memories, input/output devices or central processing units (interface circuits for specific input/output devices G06F3/00 ; multiprocessor systems G06F15/16 )

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

2 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1985.
