Terminology
The physical PCI interface that is a subset of the AGP bus driven directly by the MCH. It
supports a subset of 32-bit, 66 MHz PCI 2.0 compliant components, but only at 1.5 V (not
3.3 V or 5 V).
A two-signal serial bus used to read and write Control registers in the SDRAM’s via the
SMBus protocol
Terminology often used to describe a DIMM that contains one DRAM row. Usually one row
fits on a single side of the DIMM allowing the backside to be empty.
A connection or channel that allows data or messages to be transmitted in one direction
only.
System Management Bus. Mastered by a system management controller to read and write
configuration registers. Signaling and protocol are loosely based on I
KHz.
A means of ensuring cache coherency by monitoring all coherent accesses on a common
multi-drop bus to determine if an access is to information resident within a cache. The
Intel® 5000P MCH ensures coherency by initiating snoops on the processor busses with
the address of any line that might appear in a cache on that bus.
A sequence of transactions that occurs when the target of a lock operation is split across a
processor bus data alignment or Cache Line boundary, resulting in two read transactions
and two write transactions to accomplish a read-modify-write operation.
A transaction that consists of distinct Request and Completion phases or packets that
allow use of bus, or interconnect, by other transactions while the Target is servicing the
Request.
Stub-Series Terminated Logic
Stub Series Terminated Logic for 2.6 Volts (DDR)
Register bits, whose value remains unchanged when system is RESET
An expanded and encoded representation of a data Byte in an encoded system (for
example, the 10-bit value in a 8-bit/10-bit encoding scheme). This is the value that is
transmitted over the physical medium.
The amount of time required to transmit a symbol.
Processor-to- Intel® 5000P MCH interface. The system bus in this document refers to
operation at 266/533/1066 MHz (Bus Clock/Address/Data). The system bus is not
compatible with the P6 system bus.
A device that responds to bus Transactions. The agent receiving a request packet is
referred to as the Target for that Transaction.
A transaction that holds the bus, or interconnect, until complete, effectively blocking all
other transactions while the Target is servicing the Request.
Transaction Identifier; A multi-bit field used to uniquely identify a transaction. Commonly
used to relate a Completion with its originating Request in a Split Transaction system.
An overloaded term that represents an operation between two or more agents that can be
comprised of multiple phases, cycles, or packets.
1.
2.
See Terminology entry of “Inbound (IB)/Outbound (OB), AKA Upstream/DownStream,
Northbound/Southbound, Upbound/Downbound”
The Agent that sends a Packet across an interface regardless of whether it was the
original generator of the packet.
More narrowly, the circuitry required to drive signals onto the physical medium.
