Bitwise Reverse '><', '><='

The Bitwise Reverse operator returns least-significant bits from the first operand in their reverse order. The total number of least-significant bits to be reversed is indicated by the second operand. All other bits to the left of the reversed bits are zeros in the result. Bitwise Reverse can be used in both variable and integer constant expressions, but not in floating-point constant expressions. Example:

X := Y >< 6

If Y started out as:

%10000000 01110000 11111111 00110101

...the Bitwise Reverse operator would return the six LSBs in reverse order with all other bits zero, setting X to:

%00000000 00000000 00000000 00101011

Bitwise Reverse has an assignment form, ><=, that uses the variable to its left as both the first operand and the result destination. For example,

X ><= 8'Short form of X := X >< 8

Here, the eight LSBs of the value of X are reversed, all other bits are set to zero and the result is stored back in X. The assignment form of Bitwise Reverse may also be used within expressions for intermediate results; see Intermediate Assignments.

Note that specifying 0 as the number of bits to reverse is the same as specifying 32.
