SEDC-BASED ERROR DETECTION APPARATUS FOR PROGRAMMABLE BOOLEAN OPERATION UNIT AND SELF-CHECKING PROGRAMMABLE BOOLEAN OPERATION UNIT HAVING THE APPARATUS

摘要

PURPOSE: An error detection device based on SEDC(Scalable Error Detection Coding) for a programmable Boolean operation unit and a self-checking programmable Boolean operation unit which includes the error detection device are provided to separately perform generation of SEDC from input data, thereby implementing a combination approval system without decreasing speed of a Boolean operation or deteriorating performance of latency. CONSTITUTION: An input SEDC generator(110) receives binary input data and generates input SEDC corresponding to kinds of a Boolean operation. An error detector(120) receives the binary output data and the input SEDC and generates output SEDC. The error detector outputs an error detection result by determining identity of the output SEDC and the input SEDC. The input SEDC generator includes a 2 bit input SEDC generation unit which generates the 2 bit input SEDC as the input SEDC.
