Abstract
An apparatus for mathematical manipulation is described allowing the selective combination of shifters to shift binary numbers of various widths. Selective combination allows on-the-fly adjustment of shifters from independent to coordinated shifting operations. Selective combination allows adjustable hardware-based shifting while saving space and resources. Multiple eight-bit shifters can be configured for a variety of operand widths, such as a 32-bit width, a 24-bit width, a 16-bit width, or an eight-bit width. Multiplexers route the appropriate input data to the appropriate shifters. Bidirectional shifting is configured through a selector tree, including both shift left and shift right operations. Opcodes configure the shifters for the desired type of shift and a shifted result is generated.
