Abstract: A method for processing signals received by a plurality of receiving antennas in a radar system, for example for road safety, which emits sequences of chirp-modulated signals, wherein the received signals are mixed with local replicas of the transmitted signals so as to generate, for each receiving antenna, a sequence of detection signals. The detection signals are subjected to Fourier-transform processing and beam-forming processing for generating values of range, azimuth, and speed for at least one obstacle or “target” detected by the radar system. The method includes an acquisition process for yielding approximate values of range and azimuth of the obstacle, and a tracking process for yielding accurate range, azimuth and speed values of the obstacle itself.

Abstract: Test stimulus signals applied to at least one circuit under test are produced in a set of test stimulus generators as a function of test stimulus information loaded in test stimulus registers. Loading of the test stimulus information in the test stimulus registers is controlled as a function of test programming information loaded via a programming interface in a respective control register in a set of control registers. The test stimulus generators are activated as a function of the test programming information loaded in said control registers. Test outcome signals received from the at least one circuit under test are used to produce signature comparison signals, which are compared with respective programmable signature reference signals stored in a set of input signature registers, are produced in response to the signature comparison signals produced from the test outcome signals failing to match with the respective reference signals.

Abstract: An embodiment circuit comprises a set of input terminals configured to receive input digital signals which carry input data, a set of output terminals configured to provide output digital signals which carry output data, and computing circuitry configured to produce the output data as a function of the input data. The computing circuitry comprises a set of multiplier circuits, a set of adder-subtractor circuits, a set of accumulator circuits, and a configurable interconnect network. The configurable interconnect network is configured to selectively couple the multiplier circuits, the adder-subtractor circuits, the accumulator circuits, the input terminals and the output terminals in at least two processing configurations. In a first configuration, the computing circuitry is configured to compute the output data according to a first set of functions, and, in a second configuration, the computing circuitry is configured to compute the output data according to a different set of functions.

Abstract: An accelerator device for use in generating a list of potential targets in a radar system, such as an anti-collision radar for a motor vehicle, may process radar data signals arranged in cells stored in a system memory. A cell under test in is identified as a potential target if the cell under test is a local peak over boundary cells and is higher than a certain threshold calculated by sorting range and velocity radar data signals arranged in windows. The cells identified as a potential target are sorted in a sorted list of potential targets. The accelerator device may include a double-buffering local memory for storing cell under test and boundary cell data; and a first and a second sorting unit for performing concurrent sorting of the radar data signals arranged in windows and the cells identified as a potential target in pipeline with accesses to the system memory.
