摘要： A system and method is disclosed for efficiently managing power distribution among the various functional blocks used within portable electronic devices. The method includes allowing each functional block to be independently controlled, containing its own low-level software and power controls for setting the local power state of the functional block. For each power control domain in the implementation, hardware uses these local power states and sets the actual operating state of the power control domain accordingly.

摘要： A method and system is disclosed for accessing I/O and memory devices utilizing a DMA controller. Each device may be connected to the DMA controller through an individual channel. Clocking circuitry in the DMA may allow the DMA controller to send signals to each device at a prescribed frequency. Furthermore, the DMA controller is capable of activating and deactivating a channel clock, used in sending signals to the devices, based on the operational status of the individual devices. The DMA controller is also capable of tuning the channel clock dependant on the capabilities of any active devices. In this manner, the amount of bandwidth used during a DMA data transfer can be tailored to the specific requirements of the devices involved with the data transfer.

摘要： A method and system is disclosed for passing data processed by a DMA controller through a transmission filter. The method includes the DMA controller accessing data for transfer between an origination location in the system and a destination location in the system. The accessed data is passed through the DMA controller before being sent to the destination location. While the data is being passed through the DMA controller, it is passed through a transmission filter for processing. This processing may include the addition or removal of transmission protocol headers and footers, and determination of the destination of the data. This processing may also include hash-based packet classification and checksum generation and checking. Upon completion of the processing, the data is sent directly to a prescribed destination location, typically either a memory circuit or an I/O device.

摘要： A method and system is disclosed for transforming of data by a DMA controller without first saving the transmitted data on an intermediate medium. The method includes the DMA controller accessing data for transfer between an origination location in the system and a destination location in the system. The accessed data is passed through the DMA controller before being sent to the destination location. While the data is being passed through the DMA controller, it is transformed into a modified state. This transformation may include encryption or decryption of the data. The transformation may also include adding error correction bits to the data through an encoding process or decoding previously encoded data. Upon completion of the transformation, the data is sent directly to a prescribed destination location, typically either a memory circuit or an I/O device. Also disclosed is a DMA controller capable of performing the data transformation.
