  • Coupling a filter graph space to a network driver space
    Patent number: 7433937
    Abstract: A communication path is established that allows for communication between a filter graph space and a network driver space in a system. The communication path allows bi-directional communication between a filter graph driver in the filter graph space and a network driver in the network driver space. Addresses of data can be passed from the network driver to the filter graph driver, which allows the filter graph driver to communicate with a filter graph manager as necessary to configure the filter graph space to obtain data from the requested address. The data obtained from the address is then passed from the filter graph driver to the network driver.

  • Coupling a filter graph space to a network driver space
    Publication number: 20060036717
    Abstract: A communication path is established that allows for communication between a filter graph space and a network driver space in a system. The communication path allows bi-directional communication between a filter graph driver in the filter graph space and a network driver in the network driver space. Addresses of data can be passed from the network driver to the filter graph driver, which allows the filter graph driver to communicate with a filter graph manager as necessary to configure the filter graph space to obtain data from the requested address. The data obtained from the address is then passed from the filter graph driver to the network driver.

  • Method and system for file system management using a flash-erasable, programmable, read-only memory
    Patent number: 6256642
    Abstract: A method and system for memory management of a block-erasable flash-EProm. The system comprises a FEProm manager and a file system. The FEProm manager manages memory allocation and deallocation of the FEProm. The file system is a hierarchical directory system and uses the FEProm manager to allocate and deallocate memory. In a preferred embodiment, the FEProm manager of the present invention provides for allocation of free space, deallocation of allocated space, and reclamation of deallocated space in a block-erasable FEProm. Each block of the FEProm contains a block allocation structure, data regions, and free space. The block allocation structure contains an allocation array which describes the allocation of the data region.

    Patent number: 5898868
    Abstract: A method and system for managing memory in a block-erasable, flash-erasable, programmable, read-only memory. The system comprises a block-erasable FEProm with a block header, a block allocation table, a data storage area, a block allocation routine for selecting a block in which to store data, a data area allocation routine for selecting an entry in the block allocation table and a portion of the data storage area, and a storage routine for storing the data. The system includes a file manager to implement a file system for the block-erasable FEProm.
