Abstract: A radar sensing system includes a plurality of transmitters configured to transmit radio signals and a plurality of receivers configured to receive radio signals. First and second transmitters of the plurality of transmitters are configured to generate radio signals defined by first and second spreading code chip sequences, respectively. A first receiver of the plurality of receivers processes received radio signals as defined by a plurality of spreading code chip sequences that includes at least the first and second spreading code chip sequences. The radar sensing system also includes a code generator for generating the spreading code chip sequences.

Abstract: A radar sensing system for a vehicle has multiple transmitters and receivers on a vehicle. The transmitters are configured to transmit radio signals which are reflected off of objects in the environment. There are one or more receivers that receive the reflected radio signals. Each receiver has an antenna, a radio frequency front end, an analog-to-digital converter (ADC), and a digital signal processor. The transmitted signals are based on spreading codes generated by a programmable code generation unit. The receiver also makes use of the spreading codes generated by the programmable code generation unit. The programmable code generation unit is configured to selectively generate particular spreading codes that have desired properties.

Abstract: An adaptive clock throttle 600 interfacing a clock generator 601 generating a high speed clock and a processing engine 602 operating in response to a processing clock. Adaptive clock throttle 600 generates a plurality of lower speed clocks from the high speed clock, estimates a duty cycle of the processing engine, and selectively gates one of the lower speed clocks to the processing engine as the processing clock to increase the duty cycle of the processing engine.

Abstract: A debugging subsystem for testing a system-on-a-chip includes an embedded processor and memory and includes at least one debugging subblock monitors a bus between the processor and the memory to detect selected triggering events, counts the number of triggering events detected and when the number of triggering events reaches a predetermined threshold, generates a debugging signal.

Abstract: A method of decoding an encoded bitstream. The method includes performing a two-table lookup. A first table is addressed in response to a first plurality of bits from the bitstream. An address into a second table is generated using a value in an entry in said first table accessed in the addressing step. A value (representing the decoded value corresponding to the codeword in the bitstream) in an entry in said second table at the address from the generating step is output.

Abstract: A method for synchronizing stream processing with a locally generated system time clock is disclosed. A program clock reference is recovered from a transport layer and used to vary the frequency of the locally generated system time clock. A presentation time stamp is recovered from a packetized elementary stream derived from the transport layer. The relationship between a reference sample associated with the presentation time stamp from the packetized elementary stream and a current sample being streamed is determined relative to the system time clock. Data samples are added or subtracted from a stream of data samples being streamed in response to the step of determining to establish a relationship between the stream of samples and the presentation time stamp relative to the system time clock.
