Filed: 1981-12-16
Abstract: PURPOSE:To simplify the hardware constitution and to attain efficient use of the hardware, by modifying a check matrix of a BCH code in a prescribed form the producing a parity code. CONSTITUTION:As an example. inut data Wi is taken as W1-W8 and a parity code Pj is taken as P1-P4. Values expressed in equations are obtained at shift registers 4-7. Constants required for the calculation of the parity code P1 are outputted from ROMs and multiplication is done at multipliers 12-14. The P1 is outputted through a modulo adder 16. A switch S5 selects a feedback loop at the output of the P1 and the P1 is given to the shift register 7. Through similar operation, the production of all the parity codes of the P1-P4 is finished. Since the check matrix for a BCH code is modified into a from for ease of execution, the hardware can be simplified.

Title: Programmable controller
Inventor: ANPO TERUHISA
IPC: G05B19/05
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To reduce the processing switching frequency between general-purpose CPU and Boolean CPU and to improve arithmetic performance by masking a general-purpose CPU share instruction when an exciting condition which is stored in an accumulator and becomes an operation progress is turned off. SOLUTION: A gate 21 masks a signal by which the control register CTRL- REG3 of Boolean CPU transfers control to general-purpose CPU with the output of an operation progress stored in an accumulator ACC, namely, an exciting condition. Thus, Boolean CPU decodes a general-purpose CPU share instruction for transferring control to general-purpose CPU and NOP (instruction that nothing is processed), by making the exciting condition of an operation itself into 'OFF' by masking. When the exciting condition of a ladder program are 'ON' and 'OFF' by about 50%, the switching frequency of a private processor and general-purpose CPU can considerably be reduced.
