Embodiment Construction
[0033] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0034] Embodiments of the present application provide a method for comma detection and word alignment applicable to the JESD204B protocol, the method comprising:
[0035] Using the first register and the second register to buffer the input N-bit data respectively; wherein, the N-bit data includes at least one complete comma detection code;
[0036] Taking out N-bit data from the first register, and shifting the taken-out N-bit data for a preset number of times, and obtaining an N-bit shift sequence after each shift;
[0037] Detecting the complete comma detection code in each of the shift sequences to determine the position information of the comma detection code;
[0038] After detecting the position information of the comma detection code, generate a shift address according to the state machine; the length of the shift address is the sam...
