Title: Digital signal processor
Inventor: ABE MIKI
IPC: H03M7/30
Filed: 1990-03-05
Abstract: PURPOSE:To facilitate the control of data write/read by dividing an access unit of one buffer with a word length required for the processing, using each of the divided buffer areas for a read buffer/write buffer to apply data write/ read with only one buffer. CONSTITUTION:A word length (1 word) in the unit of access is divided at least into two by a word length (1 byte) required for the processing. Each of the divided word length is processed by a read buffer 54A and a write buffer 54R. Then in writing the data, the data in the read buffer 54A is protected and the write data is written in the write buffer 54R. In reading the data, after the data in the read buffer 54A is read, the data in the write buffer 54R is transferred to the read buffer 54A. Thus, the control of data write/read is simplified. Moreover, the required capacity of the buffer memory is much reduced more than that of a conventional digital signal processor.

Title: Automatic mode discriminating device for magnetic recording and reproducing device
Inventor: TSUBOI KOICHI
IPC: H04N9/80
Filed: 1985-03-15
Abstract: PURPOSE:To simplify the circuit constitution of the titled device and to reduce its cost by discriminating the first mode or the second mode with the output signal of a logic means which outputs a signal only when a no-recording signal generated between divided tracks on a magnetic tape and a frequency divided signal obtained by dividing the frequency of a head switching pulse in accordance with the number of parts between divided tracks are given simultaneously. CONSTITUTION:The first mode where normal picture information is recorded and reproduced and the second mode where a recording signal such as an audio signal or the like is recorded and reproduced by pulse code modulation are discriminated automatically at the reproducing time. In the second mode, a demodulated signal detecting circuit 2b outputs a pulse p8 when receiving a no-recording signal p7. A head switching processing circuit 5 outputs a pulse p9 synchronized with the pulse p8 in response to the output of a head switching detecting element 4. An AND gate 13 operates AND between pulses p8 and p9 to output a high-level signal. Changeover switches 11 and 12 are turned on by this high-level signal, and changeover switches 9 and 10 are turned off to switch the mode to the second mode.
