Abstract: A partitioned shift right logic circuit that is programmable and contains rounding support. The circuit of the present invention accepts a 32-bit value and a shift amount and then performs a right shift operation on the 32-bits and automatically rounds the result(s). Signed or unsigned values can be accepted. The right shift circuit is partitioned so that the 32-bit value can represent: (1) a single 32-bit number; or (2) two 16-bit values. A 1 bit selection input indicates the particular partition format. In operation, if the input value is not negative, then one (“1”) is added at the guard bit position and a right shift with truncate is performed. If the input is negative and the guard bit is zero, then no addition is done and a right shift with truncate is performed. If the input is negative and the guard bit is one and the sticky bit is zero, then no addition is done and a right shift with truncate is performed.
