Terminology
In this document, a ‘#’ symbol after a signal name refers to an active low signal. This means that a
signal is in the active state (based on the name of the signal) when driven to a low level. For
example, when FLUSH# is low, a flush has been requested. When NMI is high, a nonmaskable
interrupt has occurred. In the case of signals where the name does not imply an active state but
describes part of a binary sequence (such as
address
or
data
), the ‘#’ symbol implies that the signal
is inverted. For example, D[3:0] = ‘HLHL’ refers to a hex ‘A’, and D#[3:0] = ‘LHLH’ also refers
to a hex ‘A’ (H= High logic level, L= Low logic level).
The term “system bus” refers to the interface between the processor, system core logic (a.k.a. the
AGPset components), and other bus agents. The system bus is a multiprocessing interface to
processors, memory, and I/O. The term “cache bus” refers to the interface between the processor
and the L2 cache components (TagRAM and BSRAMs). The cache bus does NOT connect to the
system bus, and is not visible to other agents on the system bus.

S.E.C. Cartridge Terminology
The following terms are used often in this document and are explained here for clarification:
Pentium
II processor
—The entire product including internal components, substrate,
extended thermal plate, and cover.
S.E.C.C.
—The processor packaging technology is called a “Single Edge Contact Cartridge.”
Initial releases of the Pentium II processor are based upon this packaging technology.
S.E.C.C.2
—The follow-on to S.E.C.C. processor packaging technology. The biggest
difference from its predecessor is that it has no extended thermal plate, thus reducing thermal
resistance.
Processor substrate
—The structure on which components are mounted inside the S.E.C.C. or
S.E.C.C.2 package technology (with or without components attached).
Processor core
—The processor’s execution engine.
