Abstract: An apparatus, a method, and a computer program product are provided for time reduction in an array read access control consisting of a bitcell and a pulldown device outside of the bitcell. To reduce gate delay, this design implements a pulldown device that controls the bitcell readout. A pulldown signal is generated to activate the pulldown device. Therefore, the pulldown signal can control the pulling down of the bitcell readout without a complete read of the data array inside the bitcell. This design reduces gate delay because the dependency upon the gating logic is overridden and the number of stages is reduced.

Abstract: An apparatus, a method, and a computer program product are provided for time reduction for an array read access control consisting of a bitcell with logic gating and a pull down device included, therein. To reduce gate delay this design implements gating logic inside the bitcell. The multiplex select gating signals are brought into the bitcell, and are gated with the data array. The gating logic controls the pull down device, and MUX select signals can be produced as a readout of the bitcell. This design reduces gate delay because the dependency upon the gating logic is overridden and the number of stages is reduced.

Abstract: A method and an apparatus for performing a shift operation on an operand. The method and apparatus configures input lines to comprise a first part that includes the bits in order representing various shift amounts in a first direction and a second part that includes bits ordered representing various shift amounts in a second direction. The shift is then performed by selecting the appropriate bits from the input line to create the result.
