Abstract: Disclosed is a method of tracing a program that comprises: providing a relational database data structure defining a plurality of fields configured to store program trace information; executing a program comprising a plurality of functions including calling a function from the program; extracting first trace data of the function and storing the first trace data in a portion of the plurality of fields; and after executing the program, extracting second trace data associated with the first trace data and storing the second trace data in remaining portions of the plurality of fields.

Abstract: Disclosed is a method for reading data in a memory system including a buffer memory and a nonvolatile memory, the method being comprised of: determining whether an input address in a read request is allocated to the buffer memory; determining whether a size of requested data is larger than a reference unless the input address is allocated to the buffer memory; and conducting a prefetch reading operation from the nonvolatile memory if the requested data size is larger than the reference.

Abstract: A data storage system includes a non-volatile memory, a disc recording medium, a non-volatile memory buffer, operatively disposed between a host interface and the non-volatile memory, which stores a portion of data stored in the non-volatile memory, and a disc buffer, operatively disposed between the host interface and the disc recording medium, which stores a portion of data stored in the disc recording medium. The data storage system may be configured to receive an access address from a host operatively connected to the host interface, and sequentially determine whether the access address exists in one of the non-volatile memory buffer, the non-volatile memory, the disc buffer, and the disc recording medium, in that order.

Abstract: A method for scaling a dynamic voltage of a CPU is achieved by setting a voltage setting point for each of a plurality of code segments of a program, and profiling workload by measuring a workload variation of each of the code segments based on data that changes whenever measured, selecting a plurality of combinations, each having a plurality of voltage setting points, and calculating workload estimators corresponding to the voltage setting points of each of the selected combinations based on the workload variation measured in the workload profiling operation, selecting an optimal combination that consumes a least energy of the CPU based on the workload estimators, and determining whether a real time constraint is satisfied when an operating voltage is set based on the workload estimator corresponding to each of the voltage setting points of the optimal combination during runtime, and setting the operating voltage based on a result of the determination.
