摘要： First data to be written which is output from a function module (2) is supplied to a built-in memory (3) and a first buffer memory (11), and second data to be written which is output from the function module (2) is supplied to the built-in memory (3) and a second buffer memory (12). The first and second FIFO memories (13, 14) select and store data items having a predetermined number of outputs from a plurality of first and second output data items which are sequentially output from the first and second buffer memories (11, 12), and do not select other data items. A comparator (15) compares the data items having the predetermined number of outputs which are selected and are output by the first and second FIFO memories (13, 14) with each other.

摘要： This method is an error correction method such that, when an error is detected in a CPU with pipeline struct, a content of a register file is restored by a delayed register file which holds an execute completion state of an [Instruction N] correctly executed before this error, and a rollback control that re-executes an instruction from the [Instruction N+1] which is the next instruction of the [Instruction N] is performed. The method collects a parity check result of arbitrary Flip-Flops existing inside the CPU, and detects an error. As a result, the content of the register file is restored into the instruction execute completion state preceding to the instruction range likely to malfunction by the error, and the instruction can be roll backed from the beginning of the instruction range likely having malfunctioned by the error.
