Abstract: For example, a processor may be configured to generate compressed radar information by compressing radar values in a plurality of data bins of at least one radar processing dimension, the at least one radar processing dimension including a range dimension. For example, the processor may be configured to generate the compressed radar information by quantizing a plurality of normalized values corresponding to the radar values in the plurality of data bins. For example, a normalized value corresponding to a radar value in a data bin may be based on a normalization of the radar value with respect to a plurality of radar values in the data bin. For example, the processor may be configured to store the compressed radar information in a memory.

Abstract: For example, an apparatus may include an interference detector configured to detect interference in a radar Received (Rx) signal. The interference detector may include an input to receive Transmit (Tx) parameter information of a radar Tx signal, wherein the radar Rx signal is based on the radar Tx signal; and a processor configured to determine interference detection information of an interfering signal based on the radar Rx signal and the Tx parameter information. The interference detection information may include one or more signal parameters corresponding to a shape of the interfering signal, and interference level information to indicate a level of noise caused by the interfering signal in the radar Rx signal.

Abstract: An EC platform including a controller to control multiple integrated circuits (ICs) to synchronize an operational internal clock signal of an IC with a master clock signal. The controller generates commands for the IC to measure a phase difference or latency difference between an initial internal clock signal of the IC and an input clock signal to the IC from a parent IC. The controller further receives a difference signal from the IC to indicate the phase or latency difference. The IC includes a measurement circuit to measure the phase or latency difference, and to generate a difference signal to indicate the phase or latency difference. The IC further includes a synchronization clock generator to generate, based on the initial internal clock signal and the difference signal, an operational internal clock signal synchronized with the master clock signal. Other embodiments may also be described and claimed.
