Numbers
All numbers are expressed in decimal, except addresses and memory or register
data, which are expressed in hexadecimal. Where confusion may occur, decimal
numbers have a “D” subscript and binary numbers have a “b” subscript. The
prefix “0x” shows a hexadecimal number, following the ‘C’ programming
language convention. Thus:
One dozen = 12
D
= 0x0C = 1100
b
The multipliers “k”, “M” and “G” have their conventional scientific and
engineering meanings of x10
3
, x10
6
and x10
9
, respectively, and can be used to
define a transfer rate. The only exception to this is in the description of the size of
memory areas, when “K”, “M” and “G” mean x2
10
, x2
20
and x2
30
respectively.
In PowerPC terminology, multiple bit fields are numbered from 0 to n where 0 is
the MSB and n is the LSB. PCI terminology follows the more familiar convention
that bit 0 is the LSB and n is the MSB.
Text
Signal names ending with a tilde (“~”) denote active low signals; all other signals
are active high. “N” and “P” denote the low and high components of a differential
signal respectively.
