Abstract: An integrated circuit includes configurable logic circuit blocks that are configurable with a first configuration bitstream according to a coarse grained configuration. The coarse grained configuration implements an aggregate circuit structure of the configurable logic circuit blocks. The configurable logic circuit blocks are configurable with a second configuration bitstream according to a fine grained configuration. A total number of the first and the second configuration bits is fewer than a single fine grained configuration bitstream.

Abstract: A course correction system for a projectile can include a pre-steering trajectory determination module. The pre-steering trajectory determination module can be configured to receive a series of possible trajectories from an estimation module including a physical model defining trajectory as a function of gravitational pull and one or more launch variables, and receive a sensor data from one or more on-board sensors of the projectile. The pre-steering trajectory determination module can also be configured to reduce the possible trajectories from the estimation module to one or more refined trajectories using the sensor data, and output the one or more refined trajectories.

Abstract: An oversampling channelizer for processing overlapping data that includes a data storage unit, coupled to a data line that receives data values. The data storage unit includes a plurality of lanes, wherein each of the plurality of lanes includes dedicated memory locations and wires that store and transmit data values for a data vector of a data frame, and that store and transmit additional data values for a subsequent data vector of a subsequent data frame that includes a plurality of the data values from the data vector in the data frame. The oversampling channelizer includes a coefficient storage unit that stores a plurality of coefficient vectors for a plurality of coefficient frames. The oversampling channelizer includes a computation unit that computes a dot product of the data values for the data vectors of the data frame with coefficient values for coefficient vectors of a coefficient frame selected by a coefficient storage unit.

Abstract: A method of controlling a projectile includes initiating an execution mode if a roll control authority parameter is outside of a pre-determined operating range for a projectile. The execution mode includes bypassing a guidance command and sending a modified command to execute a coning maneuver to improve control response of the projectile. A projectile control system includes a processor operatively connected to a memory. The memory has instructions recorded thereon that, when read by the processor, cause the processor to execute the method operations described above.

Abstract: A programmable modulator (100) is programmable to operate in either of a GMSK or 8PSK mode. When operating in a GMSK mode, a signal modulating circuit 105 receives (210) a bit stream (110), maps the bit stream (110) to a phase value in complex I, Q form and applies a progressive rotation to the phase value according to GMSK specifications. The output (140) is filtered by a filter circuit (135), preferably using a complex Finite Impulse Response (FIR) filter using the standard coefficients for an 8PSK modulation to create (215) an approximate GMSK output (165). A GMSK correction circuit (150) determines a correction term that is added to the filter circuit output (165) so as to correct amplitude variations to allow the output to conform to GSM/EDGE standards. The same modulator (100) may be programmed to operate in an 8PSK mode with linear predistortion.
