  • Method and apparatus for incorporating DDR SDRAM into portable devices
    Publication number: 20080253214
    Abstract: A portable electronic device is provided which comprises (a) a memory device (42) equipped with an interface clock which is controlled by a Delay Locked Loop (DLL) such that the memory device is configured to operate in a first mode characterized by a minimum clock rate CRmin; and (b) a controller (38) adapted to cause the memory device to operate in a second mode by disabling the DLL, wherein the second mode is characterized by a nonzero clock rate Rc<CRmin.

  • System for command processing or emulation in a computer system, such as emulation of DMA commands using burst mode data transfer for sound
    Patent number: 5974478
    Abstract: A system and method for providing sound in a computer are disclosed. An audio module for controlling digitized sound I/O is included in a media stream controller. The media stream controller may also coordinate graphics and video which allows multiple media subsystems to be supported from a single bus device. A software application may initiate sound data transfer by sending a conventional DMA mode command to the media stream controller. The media stream controller activates an audio interrupt service routine which processes the request without using a conventional DMA controller. Digital sound data is transferred across a local bus using high speed burst mode block transfer commands and is buffered by the media stream controller in a display memory. Concurrently, the media stream controller may output sound data from the display memory to a sound output device using a double buffering method.
