  • Publication number: 20080071958
    Abstract: There is provided an information processing apparatus in which a CPU and an audio processing unit are coupled by a bus. The audio processing unit includes a ring buffer that temporarily retains audio data, and performs an input/output process of the audio data. An interrupt signal generator generates a buffer empty signal, when the audio data is output from a buffer in the ring buffer and the buffer is empty, decimates the buffer empty signal in accordance with a sampling frequency of audio, and then feeds the interrupt signal that survives the decimation to the CPU. The CPU, upon receiving the buffer empty signal, issues a DMA transfer instruction for writing the audio data into the empty buffer in the ring buffer.

  • Patent number: 7309645
    Abstract: The semiconductor thin film crystallization method comprises the step of forming a semiconductor thin film 14 over a substrate 10; the step of forming band-shaped portion 16 for blocking crystal growth of the semiconductor thin film in the semiconductor film or over the semiconductor film; and the step of causing an energy beam 18 of a continuous wave to scan in a direction intersecting the longitudinal direction of the portion for blocking crystal growth. The energy beam is caused to scan, intersecting the portion for blocking the crystal growth, whereby the crystal growth can be interrupted when the application region of the energy beam intersects the portions for blocking the crystal growth. Even when a solid semiconductor thin film which is not patterned in islands is crystallized, the semiconductor thin film of good crystals can be formed with high yields while the film is prevented from peeling.

  • Publication number: 20070130381
    Abstract: A DMA controller controls DMA transfer in an information processing system. Input and output devices are a transfer source or a transfer destination in DMA transfer and request DMA transfer. A DMAC activating unit is provided with an event monitoring unit and an event register. The event register registers an event subject to monitoring. The event monitoring unit detects an event generated in the input and output devices and determines whether the detected event matches an event registered in the event register. If it is determined that the events match, the event monitoring unit activates the DMA controller.

Further, a GPU performs rendering on data stored in a graphic memory according to the polygon data representing the image. Moreover, the GPU performs antialiasing on the contour and contour candidate extracted by the main CPU. Then, the GPU overwrites data representing the antialiased contour and contour candidate onto the data representing the image stored in the graphic memory.

  • Publication number: 20070016732
    Abstract: When a concentration of access requests on a specific bank occurs, the delay time is caused due to the competition among the accesses, thereby lowering the processing speed of an information processing apparatus as a whole. A data transfer arbitration unit 172 sequentially transfers data to be recorded to a memory controller 160 that records data in memory having a plurality of banks. A selector 174 selects any DMAC 170 from among a plurality of DMACs, irrespective of priority sequence of transfer service for the DMAC. A transmitter 176 transmits, to a control-side transfer unit 114, data requested to be transferred by the selected DMAC 170. The selector 174 selects consecutively the DMAC 170 so that the transfer service for the same DMAC is consecutively executed, and determines the number of consecutive selections so that a transfer across the banks of the DMAC 170 occurs by a plurality of the transfer services.
