SCALABLE ERROR DETECTION CODING(SEDC) GENERATOR, SELF-CHECKING LOOK-UP-TABLE(LUT) HAVING THE GENERATOR AND METHOD OF SCALABLE ERROR DETECTION CODING

摘要

PURPOSE: An SEDC(Scalable Error Detection Coding) generator, a lookup table including the SEDC generator, and an SEDC generation method are provided to generate SEDC for a lookup table data of in a length direction, thereby performing a unidirectional error check for the entire lookup table data. CONSTITUTION: A code length calculation module calculates the length of SEDC which is generated for binary input data. An SEDC generation module(100) includes a 2 bit input SEDC generation unit(110), a 3 bit input SEDC generation unit(120), or a 4 bit input SEDC generation unit. The SEDC generation module generates SEDC of a calculated length by an individual or a combination of the SEDC generation units.
