The hardware-accelerated Constant False Alarm Rate (CFAR) IP from EnSilica is designed for use in situational awareness radar sensors for car driver-assist apps. It allows the application processor to be freed up by providing a marked-up radar image.
The CFAR IP is matched with EnSilica’s pipelined FFT IP core to deliver a reduced data set for processor analysis when operating a continuous one bin per clock cycle. It can calculate and search more than 200k Fourier Transforms per second. EnSilica’s CFAR IP is highly configurable and includes all popular compute-intensive algorithms such as GOSCA, GOSGO, GOSSO, CA, GOCA and GOSA, which are normally applied in software and involve real-time data transform, sorting, and selection. The IP can be implemented in either FPGAs or ASICs.
The 1D and 2D CFAR IP can aid processing efficiency in driver-assist apps like advanced electronic stability control, pre-crash impact mitigation, blind spot detection, lane departure detection, and self-parking systems. It is also ISO 26262 standard compliant for functional safety for road vehicles.
