MPC105

The PowerPC-to-PCI bus bridge chip developed by Motorola for the
Ultra 603/Ultra 604 system board. It provides the necessary
interface between the MPC603/MPC604 processor and the Boot
ROM (secondary cache), the DRAM (system memory array), and
the PCI bus.

MPC601

Motorola’s component designation for the PowerPC 601
microprocessor.

MPC603

Motorola’s component designation for the PowerPC 603
microprocessor.

MPC604

Motorola’s component designation for the PowerPC 604
microprocessor.

MPIC

Multi-Processor Interrupt Controller

MPU

MicroProcessing Unit

MTBF

Mean Time Between Failures. A statistical term relating to
reliability as expressed in power on hours (poh). It was originally
developed for the military and can be calculated several different
ways, yielding substantially different results. The specification is
based on a large number of samplings in one place, running
continuously, and the rate at which failure occurs. MTBF is not
representative of how long a device, or any individual device is
likely to last, nor is it a warranty, but rather, a gauge of the relative
reliability of a family of products.

multisession

The ability to record additional information, such as digitized
photographs, on a CD-ROM after a prior recording session has
ended.

non-interlaced

A video system in which every pixel is refreshed during every
vertical scan. A non-interlaced system is normally more expensive
than an interlaced system of the same resolution, and is usually said
to have a more pleasing appearance.

nonvolatile memory

A memory in which the data content is maintained whether the
power supply is connected or not.
