Meaning
To move the content of a register either to the right or
left until fully overflowed.
A bit that indicates either a positive or a negative (the
highest-order bit).
To extend a data length in which the higher-order bits
to be extended are made to have the same sign as the
sign bit. For example, sign-extending FF
FFFF
An automatic conversion area used by C language
functions.
A sequence of characters.
To restore combined items or packed information to
its original form. Used to mean to separate 8-bit
information into two parts — 4 lower-order bits and 4
higher-order bits, to separate 16-bit information into
two parts — 8 lower-order bits and 8 higher-order bits,
and the like.
To extend a data length by turning higher-order bits to
0's. For example, zero-extending FF
results in 00FF
