Abstract: A method for treatment of a flue gas involves feeding the flue gas and a lean solvent to an absorber. The method further involves reacting the flue gas with the lean solvent within the absorber to generate a clean flue gas and a rich solvent. The method also involves feeding the clean flue gas from the absorber and water from a source, to a wash tower to separate a stripped portion of the lean solvent from the clean flue gas to generate a washed clean flue gas and a mixture of the water and the stripped portion of the lean solvent. The method further involves treating at least a portion of the mixture of the water and the stripped portion of the lean solvent via a separation system to separate the water from the stripped portion of the lean solvent.

Abstract: Cache optimization for missing data is provided. A database system receives a first request for a database record. The database system determines whether the database record is stored in a cache. The database system determines whether the database record is stored in a data store in response to a determination that the database record is not stored in the cache.

Abstract: A system provides synchronous read data sampling between a memory and a memory controller, which includes an asynchronous FIFO buffer and which outputs a clock and other control signals. An outbound control signal (e.g., read_enable) is used to time-stamp the beginning of a read access using a clock edge counter. The incoming read data is qualified based on the time-stamped value of the read_enable signal plus typical access latency by counting FIFO pops. The system performs correct data sampling irrespective of propagation delays between the controller and memory. The system may be implemented in a System on a Chip (SOC) device having a synchronous communication system.

Abstract: In a processing system, an integrated function controller (IFC) for one or more memory devices, including a NAND flash memory device, provides direct memory access (DMA) functionality for writing data to and reading data from the NAND flash memory device, thereby reducing the level of CPU intervention required to support such operations. In one implementation, the CPU stores in system memory a descriptor-based DMA operation sequence of NAND flash operations and then triggers the IFC to implement the descriptor sequence. The IFC sequentially fetches and implements individual stored descriptors without interrupting the CPU or requiring any real-time CPU intervention using, for example, a “repeat while busy” polling descriptor type. The IFC frees up the CPU to perform other system-level operations, thereby increasing the efficiency of the processing system.
