Title: Cycle generating circuit
Inventor: KIMURA MAKOTO
IPC: H03L7/18
Filed: 1996-07-24
Abstract: PROBLEM TO BE SOLVED: To generate continuous cycles with high resolution by receiving the output of a VCO at a DDS, applying this output to the other phase comparison input terminal of a PLL for transmission. SOLUTION: In a PLL circuit 60, a phase-locked loop is controlled by a phase comparator 20, so that the phase of an output signal from an external reference clock generator 10 matches the phase of an output signal from a DDS 30. As a result, in the locked state of the PLL 60, an output signal fs of the reference clock generator 10 is equal to a frequency fb of the output signal from the DDS 30. The clock frequency fb of the output from the DDS 30 can be generated at high-resolution pitches and further, even when this setting is switched, continuity in the phases of output waveforms is kept. Thus, an output period Tout of the PLL circuit 60 can be set with a (1/2<n> ) resolution of a period T for a reference period generator 10.

Title: System for reading out counter value
Inventor: HOSHI KENJI
IPC: G06F13/38
Filed: 1989-08-18
Abstract: PURPOSE:To considerably increase the processing speed by transferring upper bytes to a data bus after latching it in a latch circuit at the lower byte read timing. CONSTITUTION:Data A is counted up by one at each time of input of a clock and is changed to A+1, A+2, A+3, A+4.... Since the value of a counter 11 is always changed even after lower four bytes 13 are transferred to a data bus 14, the counter value can be changed until one remaining upper byte 12 is transferred to the data bus 14. Consequently, it is latched in a latch circuit 15 at the timing when lower bytes 13 are read out to a multiplexer 16. One upper byte 12 latched in the circuit 15 is transferred to the multiplexer 16 at the next timing. Since one remaining upper byte 12 is latched in the circuit 15 in this manner, the value of one upper byte 13 which s not changed is transferred to the multiplexer 16 though the value of the counter 11 is changed to the next value. Required data is sent to the bus 14 from the multiplexer 16.
