Patent number: 7895466Abstract: An integrated circuit includes a DMA controller for performing conventional DMA transfers and for backing-up and restoring data during low power events. The integrated circuit includes one or more processor components, one or more peripheral components, a power management circuit and the DMA controller. The power management circuit manages power control within the integrated circuit. The DMA controller includes a DMA engine for executing DMA transfers between different ones of the components and memory based on configuration parameters provided to the DMA engine. A detection circuit configured determines if the power management circuit initiates a power state change. The DMA controller also has circuitry for providing a first set of configuration parameters to the DMA engine if no change in power state is detected and overriding the first set of configuration parameters with a second set of configuration parameters if a change in power state is detected.Type: GrantFiled: September 2, 2008Date of Patent: February 22, 2011Assignee: Telefonaktiebolaget L M Ericsson (PUBL)Inventor: David Barrow

Publication number: 20070168579Abstract: PPP frame encapsulation of IP frames—including FCS calculation, character escaping, and HDLC flag insertion—is performed by hardware acceleration circuits within a DMA module as part of a DMA transfer autonomously of a processor. Software may preprocess the IP packets prior to the hardware-accelerated processing. The hardware acceleration in the DMA module may additionally decapsulate PPP frames—including FCS calculation and comparison for error detection, escaped character recovery, and frame boundary detection—to assist in the formation of IP packets. The hardware-accelerated PPP framing may be particularly useful when a mobile terminal provides internet access, through a wireless communication network over packet data channels, to an attached peripheral device, such as a computer.Type: ApplicationFiled: September 20, 2005Publication date: July 19, 2007Inventors: William Croughwell, David Barrow

Publication number: 20070023738Abstract: A lead free, thick film heating element. Known thick film heating elements contain environmentally hazardous material such as lead. This is particularly problematic when manufacturing thick film heating elements, as lead is often used in thick film formulations to allow the glass-based thick film to be processed at low firing temperatures. Using composite sol gel technology, the present invention provides a method to produce a lightweight mica-based thick film heating element based on thick film materials that are free from lead or cadmium. This mica-based element is lightweight, has the performance advantages of a thick film heating element, and may be processed at a low temperature using thick film materials.Type: ApplicationFiled: July 18, 2006Publication date: February 1, 2007Inventors: Timothy Olding, David Barrow, Mary Ruggiero

Publication number: 20050080999Abstract: Memory interface for multi-CPU system provides predefined time slots in which each CPU may access an external memory. The time slot assigned to each CPU may be defined according to the expected memory requirements of the CPU. In this way, each CPU is guaranteed to have a certain amount of dedicated bandwidth to the external memory. The predefined time slots also allow the latency of the system to be known, which is useful for real-time oriented applications. Moreover, each CPU may use its own clock during its allotted time slot to control the external memory, thus accommodating various clock domains in the system. Memory refresh and data protection functions are also provided. This Abstract is provided to comply with rules requiring an Abstract that allows a searcher or other reader to quickly ascertain subject matter of the technical disclosure. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.Type: ApplicationFiled: May 27, 2004Publication date: April 14, 2005Inventors: Fredrik Angsmark, Tord Nilsson, David Barrow
