Abstract: Chemical vapor deposition (CVD) is enhanced by compensating for a depleted gas concentration zone in a CVD reactor. According to an example embodiment of the present invention, a chemical-vapor deposition (CVD) gas injector is adapted to supply gas to a CVD chamber in a manner that enhances the properties of deposited films. The injector has a gas inlet coupled to a gas source and supplies gas from the source to the CVD system via at least one gas outlet. The injector is adapted to deliver gas in a manner that sufficiently maintains uniform supply of the gas in a zone of the CVD system that would exhibit a depleted gas supply absent the injector. The uniform gas supply improves the CVD process in various manners, including making possible the deposition of films having uniform properties, such as reflectivity, extinction coefficient, thickness and refractive index.

Abstract: A system and method for providing a desired degree of fairness of access to data transfer resources by a plurality of command-initiating bus agents. A bus arbiter allocates general ownership of the bus to one of a plurality of bus agents, and a fairness module imposes a desired degree of fairness to the data transfer resources by mandating data transfer resource access to bus agents whose commands have been subjected to a retry response. The degree of fairness is controllable, in order to appropriately balance the desired throughput and data transfer resource allocation for a particular application.

Abstract: A method and apparatus for testing data coherency in a file system implemented on a data processing arrangement. A record of file addresses is maintained for addresses that are not targeted by write operations, and word address ranges for write operations are selected from the record of file addresses not targeted by other write operations. A plurality of asynchronous write operations that specify word address ranges and data to be written are issued. For each completed write operation, an asynchronous read operation that references the address range of the completed write operation is issued. The data returned from the read operation is verified against data issued in the completed write operation. The record of file addresses not targeted by write operations is updated when the verifying step is complete.

Abstract: A memory processing approach involves implementation of memory status-driven access. According to an example embodiment, addresses received at an address buffer are processed for access to a memory relative to an active location in the memory. Addresses corresponding to an active location in the memory array are processed prior to addresses that do not correspond to an active location. Data is read from the memory to a read buffer and ordered in a manner commensurate with the order of received addresses at the address buffer (e.g., thus facilitating access to the memory in an order different from that received at the address buffer while maintaining the order from the read buffer).

Abstract: A data transfer system uses a data buffer and individual control of each storage location within the data buffer for improved control of data block transfers. The storage locations are assigned deallocate, active, or valid assignment bands to enable transfer control of the data blocks within the system. The deallocated storage locations are returned to an allocation pool for use as a future resource, where the active and valid assignment bands remain unavailable until deallocated. Error checking and depth control prohibit consecutive allocation or deallocation assignments as well as overflow.
