Abstract: PURPOSE:To shorten considerably a decision by majority discrimination processing time to improve the processing efficiency of software by performing majority discrimination in byte or word units up to a certain discrimination reference and performing majority discrimination in bit units if the discrimination reference is not satisfied. CONSTITUTION:A received data input is stored in a buffer memory part 1, and contents of this information are sent to a byte unit majority discrimination processing part 12 to discriminate whether byte units are available or not in an availability discriminating part 13; and if they are availabe, contents are outputted through an output buffer memory part 14. If it is discriminated that the byte unit information is not available, the availability discriminating part 13 opens a bit unit decision by majority discriminating part 15 and sends byte unit information in the buffer memory part 11 to the part 15, and the decision by majority discrimination of three out of five is performed in each bit unit for the byte by an availability discriminating part 16, and the result is outputted through the output buffer memory part 14 if it is judged to be available; but if it is judged to be no available, information is processed as unavailable information.
Patent JP-H03242776-A (JP)
Title: Microcomputer
Inventor: KURODA YUKIE
IPC: G06F15/78
Filed: 1990-02-20
Abstract: PURPOSE:To improve the processing efficiency of a CPU by providing a microcomputer with a means for switching the contents of data to be outputted to the external at an optional timing independently of the control of a central processing unit(CPU) after setting up output data by the CPU. CONSTITUTION:The CPU 1 sets up data in a polarity setting buffer 8 through buses 3, 4 and instructs timers A, B to start counting. When the timer B starts counting, initial data are set up in a toggle flip flop(FF) 7 and then the output Q and the polarity of the outputs Q of the FF 7 is inverted in each overflow of the timer A. Thereby, the polarity of a port output can be switched at real time in response to each overflow of the timer A independently of the CPU 1. Since it is unnecessary for the CPU 1 to always set up the switching timing of port output data, delay time for switching the port output data can be removed.
