The default use of the Cyclic Redundancy Check (CRC) component is to compute the CRC from a serial bit stream of any length. The input data is sampled on the rising edge of the data clock. The CRC value is reset to 0 before starting or can optionally be seeded with an initial value. On completion of the bitstream, the computed CRC value may be read out.
-
1 to 64 bits
-
Time Division Multiplexing mode
-
Requires clock and data for serial bit stream input
-
Serial data in, parallel result
-
Standard [CRC-1 (parity bit), CRC-4 (ITU-T G.704), CRC-5-USB, etc.] or custom polynomial
-
Standard or custom seed value
-
Enable input provides synchronized operation with other components
