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.

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.
