Title: Serial data processor
Inventor: AOKI MITSUE
IPC: G06F13/38
Filed: 1990-10-08
Abstract: PURPOSE:To easily deal with an abnormality even when abnormality is generated by detecting the abnormality by a second processor itself when not outputting a reception confirming signal due to the abnormality of the second processor receiving data, and generating an interruption signal. CONSTITUTION:An interruption generating circuit 27 discriminates whether an ACKT flag 281 is set or not when a reception confirming signal line 44 becomes active. At this time, when the ACKT flag 281 is set, a second processor 2 as a receiving side is considered to output the reception confirming signal by itself, and the reception abnormality interruption signal line 43 remains nonactive. Conversely, when the ACKT flag 281 is not set, though the second processor 2 as the receiving side itself does not output the reception confirming signal, the reception confirming signal is considered to be detected, and the reception abnormality interruption signal line 43 is made active. Thus, even when the abnormality is generated, it is possible to easily deal with abnormality.

Title: D/a conversion method
Inventor: TAKAYAMA TAKEYUKI
IPC: H03M1/82
Filed: 1990-10-08
Abstract: PURPOSE:To eliminate second harmonics component having been unavoidable in a conventional D/A conversion method by adopting this method such that a center position of a synthesized pulse output has always a prescribed phase difference with respect to a timing signal. CONSTITUTION:An input digital signal 1 inputted synchronously with a timing signal 6 is converted into parallel signals 31, 32 corresponding to a prescribed pulse waveform by ROMs 8, 9. Then a parallel/serial converter 4 applies parallel/serial conversion to parallel signals 31, 32 outputted from the ROMs 8, 9 by a timing signal 6 and a clock signal 7 to convert the signals 31, 32 into pulse outputs 41, 42. Then the pulse outputs 41, 42, are given to a subtractor 10, in which they are subtracted, thereby allowing the digital signal 1 to be PWM- converted into a synthesis pulse output 11. In this case, the center position of the synthesis pulse output 11 always has a prescribed phase difference with respect to the timing signal 6. Thus, no second harmonics are produced in the synthesis pulse output 11.
