Title: Method for arbitrating bus using right
Inventor: KAMIMURA AKITOSHI
IPC: G06F13/37
Filed: 1989-10-31
Abstract: PURPOSE:To almost uniformly allocate the acquisition right of bus using right to respective bus masters by applying the acquisition right from a bus master positioned on the downstream of a bus master cancelling bus using right after previously acquiring the bus using right in the case of arbitrating a new bus using right. CONSTITUTION:When any one of bus masters 51 to 53 requests bus use, a system bus controller 50 simultaneously outputs a bus using right permission available signal to all the bus masters 51 to 53. When the bus master storing bus using right acquisition history receives the bus using right permission available signal, the bus master erases the bus using right acquisition history and transfers the bus using right permission available signal to its lower bus master. Thereby, the bus master generating a bus using request and then receiving the bus using right permission available signal can acquire the bus using right. Consequently, deflection allowing only the specific bus master out of the plural ones 51 to 53 to easily acquire the bus using right can be removed.

Title: Moving signal control circuit
Inventor: TANAKA YUTAKA
IPC: H04N19/85
Filed: 1987-11-10
Abstract: PURPOSE:To prevent the missing of moving detection and the erroneous detection of movement by generating a control signal to process a moving signal, when the total sum of the quantity of moving information in one field or one frame exceeds a prescribed numerical value, for all the picture elements in one or more subsequent fields. CONSTITUTION:A moving detection circuit 1 outputs a moving signal that goes to '1' at a picture element judged to be moving but goes to '0' at a picture element judged to be still. At a picture element whose moving signal is '1', the value (integrated counted value) of the content (x) of an up-counter 2 increases by one by synchronizing with a clock input. When the value (x) of the counter 2 reaches its maximum value xm, the counter 2 generates a carry output, and by this output, the output of a flip-flop 4 goes to '1'. The flip-flop also is reset by a loading pulse. An output from the flip-flop 4 goes to an input to a latch circuit 5 clocking the loading pulse, and an output from the circuit 5 is made an input to an OR gate 6. An output from the OR gate 6 is made a moving control signal to control the moving/still switching of a moving- adaptive type signal processor.
