Publication number: 20110314197Abstract: Each of a plurality of master devices outputs a speed grade signal indicating a data transfer speed with a data transfer request. An arbiter arbitrates transfer requests and speed grade signals from the plurality of master devices. A clock enable generation circuit generates a clock enable signal with a varying ratio of a valid level according to the speed grade signal arbitrated by the arbiter. A slave device operates upon receiving a clock signal when the clock enable signal is at the valid level, and transfers data according to the transfer request arbitrated by the arbiter. Accordingly, the frequency of the clock signal which causes the slave device to operate may be changed for each transfer request, and a fine control of the power of the slave device may be easily performed. As a result, power consumption of the data processing system may be finely controlled.Type: ApplicationFiled: March 7, 2011Publication date: December 22, 2011Applicant: FUJITSU SEMICONDUCTOR LIMITEDInventor: Akinori HASHIMOTO

Patent number: 6748037Abstract: A digital broadcasting receiver is provided which can reproduce a carrier quickly and capture a desired signal at high speed. A carrier reproduction phase error detection circuit (6) detects a phase error voltage in accordance with a demodulation output obtained by demodulating a demodulated wave of a modulated wave during a predetermined section in a header section.

Patent number: 6639951Abstract: A digital demodulator that eliminates the need for an absolute phase circuit is provided. In a digital demodulator for a digital broadcasting receiver that receives digital time-division multiplexed signals of different types of modulation, the demodulated baseband signal is selectively inverted by an inverter (7) according to an inversion command signal “0” or “1” that is output from an inversion decision circuit (6) depending on a BPSK signal of a known pattern. A phase error detector (8) for carrier reproduction determines the phase error voltage based on the phase difference between the absolute phase and the phase of the signal point of the demodulated baseband signal output from the inverter (7). The phase error voltage is passed through a carrier filter (9), including a low-pass filter, to control the carrier frequency so that carrier reproduction can be carried out with the phase at the signal point being coincident with the point of phase convergence.Type: GrantFiled: May 18, 2000Date of Patent: October 28, 2003Assignee: Kabushiki Kaisha KenwoodInventors: Hisakazu Katoh, Akinori Hashimoto, Tomohiro Saito, Fumiaki Minematsu, Kenichi Shiraishi, Akihiro Horii, Shoji Matsuda, Soichi Shinjo

Patent number: 6526107Abstract: There is provided a synchronization acquiring circuit for stably acquiring frame synchronization without pseudo-synchronization lock when the frame synchronization is acquired in reception at the time of a low C/N. The synchronization pattern of a received frame is detected by a frame synchronization detecting circuit 2.
