Format:

SRLV ry, rx

Purpose:

Shift Word Right Logical Variable

To execute a logical right-shift of a word by a variable number of bits.

Description:

GPR[ry] = GPR[ry] >> GPR[rx] (logical)

The 32-bit contents of GPR ry are shifted right, and zeros are inserted into the emptied high-order bits;the word result is placed back in GPR ry. The 5 low-order bits of GPR rx specify the shift amount.

Restrictions:

None

Operation:

s = GPR[Xlat(rx)]4..0
temp = 0s || GPR[Xlat(ry)]31..s
GPR[Xlat(ry)] = temp

Exceptions:

None
