    摘要： Embodiments of the invention enable a storage cache, comprising flash memory devices, to have direct block access to the flash such that the physical block addresses are presented to the storage system's cache layer, which thereby controls the storage cache data stream. An aspect of the invention includes a caching storage system. The caching storage system comprises a plurality of flash memory units organized in an array configuration. Each of the plurality of flash memory units includes at least one flash memory device and a flash unit controller. Each flash unit controller provides the caching storage system with direct physical block access to its corresponding at least one flash memory device. The caching storage system further comprises a storage cache controller. The storage cache controller selects physical block address locations (within a flash memory device) to be erased where data are to be written, issues erase commands to a flash unit controller corresponding to the selected physical block address locations, and issues page write operations to a set of erase blocks.

    摘要： According to one embodiment, a method for using flash memory in a storage cache comprises receiving data to be cached in flash memory of a storage cache, at least some of the received data being received from at least one of a host system and a storage medium, selecting a block of the flash memory for receiving the data, buffering the received data until sufficient data has been received to fill the block, and overwriting existing data in the selected block with the buffered data. According to another embodiment, a method comprises receiving data, at least some of the data being from a host system and/or a storage medium, and sequentially overwriting sequential blocks of the flash memory with the received data. Other devices and methods for working with flash memory in a storage cache according to various embodiments are included and described herein.

    摘要： A method and computer program product for code coverage utilizing efficient dynamic mutation of logic (EDML) are provided. A source code is read, and instrumentation points are located. Self Modifying Code (SMC) is inserted at the instrumentation points producing instrumented code. Additional functions are inserted in the source code to enable read and/or reset of code coverage statistics. The instrumented code is compiled, and executables are run for a period of time during which zero or more instrumentation points are executed. In response to executing instrumentation points, instructions are executed to record execution of the instrumented code. Instructions of the instrumented code overwrite themselves at certain points so that a next execution of the instrumentation points skips over the instrumented code at the certain points. Code coverage statistics are gathered and recorded. The code coverage statistics are reset to begin another period of time for gathering code coverage statistics.
