BCD

Binary-coded decimal notation

bi-endian

A byte ordering of either big-endian or little-endian supported by a processor.

(Byte)		1	2	3
0x1A2B3C4D	1A	2B	3C	4D	Big
	4D	3C	2B	1A	Little

Note that the byte is endianless; that is, whether it is big-endian or little-endian, the MSB (most significant bit) is bit #7 and the LSB (least significant bit) is bit #0.

big-endian

The byte ordering typically used by large mainframes. For purposes of this book, that would include the EE, VU, PowerPC-AltiVec, and PowerPC-Gekko processors.

		1	2	3
0x1A2B3C4D	1A	2B	3C	4D

blit

The process of transferring one or more blocks of data. The etymology of the word is Bacon, Lettuce, and Interactive Tomato.

A methodology used by a processor to predict at a conditional jump whether an instruction branch will be taken or not.
