Abstract: A method for specifying stateful, transaction-oriented systems is provided. The method initiates with designating a plurality of primitive FlowModules. The method includes defining at least one FlowGate within each of the plurality of FlowModules, wherein each FlowGate includes a non-interruptible sequence of procedure code, a single point of entry and is invoked by a named concurrent call. An Arc is designated from a calling FlowGate to a called FlowGate and a Signal is generated for each named invocation of the called FlowGate. A Channel is defined for carrying the Signal. Methods for synthesizing a semiconductor device and routing signals in the semiconductor device are provided.

Abstract: An audio signal enhancement device is provided. The device includes a first and a second microphone, placed as close together as possible, the first and second microphone having receiving surfaces facing in opposing directions. The first and second microphones receive a desired target audio signal originating in the proximity of the microphones and undesired noise signals not originating in the proximity of the microphones. The acoustic pressure gradient from the desired target signal between the first and the second microphones is greater than that from the noise signals. Signal processing logic is provided. The signal processing logic is configured to firstly generate a proximity-indicator signal and a pre-target-estimate signal through a combination of output from the first microphone and output of the second microphone.

Abstract: An apparatus for performing in-memory computation for stateful, transaction-oriented applications is provided. The apparatus includes a multi-level array of storage cells. The storage cells are configurable for a read access from one of a plurality of access data paths. The plurality of access data paths are also configurable for a write access from one of the plurality of access data paths. The multi-level array is capable of being configurable into logical partitions with arbitrary starting addresses. The apparatus further includes a compute element in communication with the multi-level array over the plurality of access data paths, the compute element configured to issue a plurality of memory accesses to the multi-level array through the plurality of access data paths. Methods for programming a multi-level array of storage cells and for processor design are also provided.

Abstract: A semiconductor memory device is provided. The semiconductor memory device includes a plurality of memory cells arranged in multiple column groups, each column group having, a plurality of columns and a plurality of external bit-lines for independent multi-way configurable access. The column group having a first, second, and third level of hierarchy in the external bit-lines. The first level of the hierarchy provides connectivity to the plurality of memory cells. The second level of the hierarchy provides a first splicer for multiplexing data to and from each of the columns in the column group to an intermediate bit-line. The third level of the hierarchy includes a second splicer for multiplexing data to and from multiple external access paths to the intermediate bit-line. A structurally reconfigurable circuit device and methods for designing a circuit are also provided.
