IPC: G10L21/003
Filed: 1995-02-28
Abstract: PURPOSE: To prevent interruption of reproduced sound by making a changeover between a write priority and a read priority depending on whether the arrangement of data to be inputted to memory is in the normal direction or the reverse one when a read request and a write request to memory occur concurrently. CONSTITUTION: Reproduced data is written into a DRAM of a sound recording/ reproducing device such as VTR with a speed faster than the reading speed through a DRAM controller. The DRAM controller is provided with a judging circuit which includes logic gates, 25 to 24, 26 and D type EF 20, 25, etc., and to which UPDOWN signals showing whether the direction of reproduction is normal or reverse, switching signals SW inversed every read/write operation, and judgment timing signals JUDGE outputted in one byte unit are supplied. When a read request RREQ and a write request WREQ2 are concurrently generated, a first priority in outputting is given to the write enable signal WEB at the time of reproduction in the normal direction and to the read enable signals REB at the time of reproduction in the reverse direction to prevent reproduced sound from being interrupted.

IPC: G04G5/00
Filed: 1982-03-15
Abstract: PURPOSE:To reduce the number of switches for setting time by discriminating the operation mode of one setting switch to selectively performing the counting up and correction of a lower digit alone and the carry to an upper digit. CONSTITUTION:When a setting switch 1 is operated in a range of t<T1, a pulse 11 is outputted through a monostable multivibrator 10 to add +1 to counts of a first counter 2, while the second counter 3 fails to be counted up. When the setting switch 1 is operated in the range of t>=T1, a non-stable multivibrator 12 outputs a repeated pulse 13 to be inputted into the first counter 2. As the counts thereof reaches 9, switching elements 14 and 15 are turned OFF to halt the pulse input to the first counter 2. When the setting switch is continued to be depressed for over 2 sec, a pulse is inputted to the first counter 2 while a carry signal is applied to the second counter 3.
