|20140181164||SELECTIVELY COMBINABLE SHIFTERS - 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. Opcodes configure the shifters for the desired type of shift and a shifted result is generated.||06-26-2014|
|20140164457||EXTENSIBLE ITERATIVE MULTIPLIER - An extensible iterative multiplier design is provided. Embodiments provide cascaded 8-bit multipliers for simplifying the performance of multi-byte multiplications. Booth encoding is performed in the lowest order multiplier, with the result of the Booth encoding then provided to higher order multipliers. Additionally, multiply-add operations can be performed by initializing a partial product sum register. Configurable connections between the multipliers facilitate a variety of possible multiplication options, including the possibility of varying the width of the operands.||06-12-2014|
|20140049288||HUM GENERATION CIRCUITRY - Systems and methods for clock generation and distribution are disclosed. Embodiments include arrangements of synchronization signals implemented using a mesh circuit. The mesh circuit is comprised of a plurality of null convention logic (NCL) gates organized into rings. Each ring shares at least one NCL gate with an adjacent ring. The rings are configured in such a way that each ring in the mesh operates synchronously with the other rings in the mesh.||02-20-2014|
|20130249594||IMPLEMENTATION METHOD FOR FAST NCL DATA PATH - An implementation method for a fast Null Convention Logic (NCL) data path includes a pipeline that is assembled from gates of various types of NCL. Self-ready flash NCL gates include a one-shot circuit to reset the gates to a null state and prepare the gates for the next wave of asserted data. In one embodiment, the one-shot circuit creates a flash pulse inside a gate in response to a change of a flash input line and ends the flash pulse in response to the gate output being reset to a null state. Conventional logic can be included in the data path as well.||09-26-2013|
|20130214814||SELF-READY FLASH NULL CONVENTION LOGIC - A self-ready flash null Convention Logic (NCL) gate includes a one-shot circuit to create the flash timing to reset the gate to a null state. The one-shot circuit may be any type of circuit to generate a pulse in response to a change of state of an input line. In one embodiment, the one-shot circuit may start the pulse in response to a change of a flash input line and end the pulse in response to the NCL output being reset to a null state.||08-22-2013|
|20130214813||MULTI-THRESHOLD FLASH NCL CIRCUITRY - Multi-threshold flash Null Convention Logic (NCL) includes one or more high threshold voltage transistors within a flash NCL gate to reduce power consumption due to current leakage by transistors of the NCL gate. High-threshold voltage transistors may be added and/or may be used in place of one or more lower voltage threshold transistors of the NCL gate. A high-Vt device is included in the pull-up path to reduce power when the flash NCL logic gate is in the null state.||08-22-2013|
