| Abstract(in English) | The decrease in the soft error tolerance in processors becomes a problem. The soft error is a phenomenon that the circuit does not malfunctions temporarily by the noise. To improve reliability, there is parity and ECC in the memory. However, it is difficult to add the error detection/correction code in combinational circuits. It enables the error detection by multiplexing the execution program. It has the problem that increases the energy consumption. In this research, We investigate the reliable datapath by reusing execution results. It does not execute the same instruction in detail. It maintains the result in a table, and obtains the result without ALU, The table with ECC can have reliability. The energy consumption depends on the table composition. Result of examining table composition, it can adjust the amount of the increased energy consumption to 6.3%. |
