Title: Color demodulator control unit
Inventor: WASHIJIMA NORIYUKI
IPC: H04N9/465
Filed: 1979-04-19
Abstract: PURPOSE:To release stop of the operation of a multivibrator by stopping signal supply to the line discrimination signal generating circuit after stopping the operation of the multivibrator in case of occurrence of the line discrimination signal. CONSTITUTION:If the phase relation between switching signal fH/2 having the half frequency of the horizontal frequency and transmission line information is not correct, a positive-polarity signal is generated from comparator 3. After its positive DC components are detected to supply the reset signal, which stops the operation, to multivibrator 1, signal supply to line discrimination signal generating circuit 2 is stopped to stop generation of the reset signal. Consequently, when the phase becomes correct, DC components of the output of comparator circuit 3 becomes zero, and multivibrator 1 starts the operation again, and thus, permanent stop of the operation does not occur.

Title: Microprocessor function extending system
Inventor: HATAKEYAMA OSAMU
IPC: G06F9/46
Filed: 1986-03-05
Abstract: PURPOSE:To execute the extending instruction without correcting completely a program by using an interruption permitting flag, generating a step interruption for one instruction execution and investigating the instruction to be executed next by the processing routine. CONSTITUTION:In a microcomputer system where a closely linked processor (coprocessor) is not connected, when a program including an extending instruction is executed, the interruption permitting flag is turned on before the execution of a program. As such a result, a step interruption is generated for one instruction execution, after an instruction-1 is executed, the control is shifted to a step interruption processing routine, and then, automatically the step interruption is prohibited. The control is executed so that at the time of the occurrence of the step interruption, it can be judged whether or not the instruction to be executed next is the extending instruction, in case of the extending instruction, the processing of the software emulator of the coprocessor is executed and when the instruction is not the extending instruction, the step interruption can be removed as it can. Thus, the extending instruction can be executed without correcting completely the program.
