Title: Viterbi decoder
Inventor: NAKAMURA TADASHI
IPC: H03M13/23
Filed: 1987-03-18
Abstract: PURPOSE:To decrease the access frequency to a trace memory and to increase the decoding speed by dividing a single highest priority path trace period into plural decoding cycles for decoding operations and then performing comparison between a past highest priority path read out of the trace memory and a highest priority path obtained newly for check of the coincidence between both paths. CONSTITUTION:It is supposed that the path tracing operation carried out by a coincidence comparison type path tracer 11 does not end within a single decoding cycle and continues in plural decoding cycles with a dummy node number written into a trace memory 9 in each of continuous decoding cycles as the head information on a highest priority path. If the coincidence is detected from comparison and the tracing action is restarted for a new highest priority path, a dividing type path tracing action is carried out at a part where a dummy node number is written by switching selectors 14-17 toward a division type path tracer 12. In this division type path tracing mode, no comparison process is carried out and therefore it is not required to read the node number out of the memory 9 and no access time is needed to the node number. Thus the decoding speed is increased.

Abstract: PURPOSE:To stop the feed of a tape and to improve the safety of a magnetic recording/reproducing device by actuating an automatic stopping means in case the tape is wound around a capstan, etc. or a motor is locked by utilizing the outputs of two time constant circuits provided to a tape end detecting circuit. CONSTITUTION:A tape end detecting circuit 3 receives the output from a Hall IC2 which detects the change of a magnetic pole due to the revolution of a magnet 1. The circuit 3 consists of an end detecting circuit 3a containing a time constant circuit having a time constant T1 and an end detecting circuit 3b containing a time constant circuit of a time constant T2 longer than T1. The outputs of the circuits 3a and 3b are set at level 0 after T1 and T2 from a time point ts when the reset pulse given from the IC2 is stopped. When the tape reaches its end and the revolution of the reel drive disk is stopped, the output of the circuit 3a is set at level 0 after T1. Then the direction where the tape is driven at a constant speed is switched. The output of the circuit 3b is set at level 0 after T2 from a time point when the reel drive disk has no revolution. Thus a transistor 10 is set under a non-conduction state and then automatically stopped.
