Classification: CPC H | IPC H

Claim 0:
1. A system comprising:
a camera configured to capture an image frame;
an image data interface coupled to, and configured to obtain the image frame from, the camera; and
an integrated circuit coupled to the image data interface, the integrated circuit including:
a data movement fabric coupled to the image data interface;
a hardware accelerator (HWA) coupled to the data movement fabric and configured to:
generate second image data based on first image data associated with the image frame by at least performing a census transform on the first image data, arranging the second image data into a bit string, and determining a binary value based on the bit string; and
determine a cyclic redundancy check (CRC) value based on the binary value generated from the census transform;

a memory interface coupled to the data movement fabric;
memory coupled to the memory interface; and

a host device interface configured to transmit the CRC value to a host device to detect an image frame freeze condition based on the CRC value.
