A method includes receiving first data at a controller of an ADAS via a first virtual channel of a camera serial interface 2 (CSI-2) data interface. The method also includes receiving second data at the controller of the ADAS via a second virtual channel of the CSI-2 data interface. The method includes storing the first data at a first address in a memory, the first address specified by the first virtual channel. The method also includes storing the second data at a second address of a control register, the control register specified by the second data. The method includes performing a test using the first data and the second data.

A non-transitory computer-readable medium stores instructions executable by a processor to process data from a radar circuit having multiple antennas. The instructions direct the processor to iteratively access a N×M range matrix indexed by N velocity bins and M antenna combinations to obtain unique X×Y range slices of the N×M range matrix, in which X is a lesser multiple of N and Y is a lesser multiple of M; iteratively access a M×S steering matrix indexed by the M antenna combinations and S hypothesis angles to obtain unique Y×Z steering vector slices of the M×S steering matrix, in which Z is a lesser multiple of S; combine the first X×Y range slice with the first Y×Z steering vector slice to form an intermediate slice, combine each subsequently accessed X×Y range slice and corresponding Y×Z steering vector slice and add the combination to the intermediate slice until a beamforming slice is formed that incorporates data for all M antenna combinations for the particular set of X velocity bins and Z hypothesis angles. An operation is then performed on the beamforming slice.

Beamforming hardware accelerator for radar systems

A non-transitory computer-readable medium stores instructions that cause processors to obtain an N&#xd7;M range matrix comprising radar data indexed by velocity and antenna and an M&#xd7;S steering matrix comprising expected phases indexed by antenna and hypothesis angle. For each unique X&#xd7;Y range slice corresponding to a particular set of X velocities, processors store the particular range slice in a first buffer. For each unique Y&#xd7;Z steering slice corresponding to a particular set of Y antenna, processors store the particular steering slice in a second buffer. The processors perform beamforming operations on the range, steering, and intermediate slices, storing the result in a third buffer as the intermediate slice. After each steering and range slice for the particular set of X velocities has been iterated through, the processors store the intermediate slice as a beamforming slice for the particular set of X velocities and the hypothesis angles.

Methods, apparatus, and systems to replace values in a device are disclosed. An example apparatus includes a processor and a replacement generator coupled to the processor and configured to detect an access, by the processor, of a first instruction at a first address in a first memory, in response to the detected access, compare the first address to a set of trigger instruction address records in a second memory, wherein the set of trigger instruction address records includes a first trigger instruction address record that is associated with a first replacement address record and a first replacement value record, and based on the first address corresponding to the first trigger instruction address record, replace a first value at a second address in a third memory specified by the first replacement address record with a second value specified by the first replacement value record.

Methods, apparatus, and systems to replace values in a device

A system includes a volatile storage device, a read-only memory (ROM), a memory built-in self-test (BIST) controller and a central processing unit (CPU). The CPU, upon occurrence of a reset event, executes a first instruction from the ROM to cause the CPU to copy a plurality of instructions from a range of addresses in the ROM to the volatile storage device. The CPU also executes a second instruction from the ROM to change a program counter. The CPU further executes the plurality of instructions from the volatile storage device using the program counter. The CPU, when executing the plurality of instructions from the volatile storage device, causes the ROM to enter a test mode and the memory BIST controller to be configured to test the ROM.

A digital system includes a spur calculator that computes harmonics of a frequency of a digital clock signal and that identities a harmonic that lies in a frequency band of operation of a radio frequency circuit. A duty cycle computation module receives the harmonic and computes a duty cycle for the harmonic. Further, a clock generator that is coupled to the duty cycle computation block generates a digital clock signal of the frequency and with the duty cycle such that amplitude of spur caused due to the harmonic is suppressed.
