    • A method for tracing a program with a relational database is provided to improve performance of the program by tracing function calls, searching program paths, and solving bottleneck with a parent function and call stack information of a specific time point. First trace data, which is used for tracing a program, of a function call is extracted from the program during execution of the program and is stored to a part of a field of a relation database. Second trace data is extracted by tracing the remaining part of the field from the stored first trace data of the function call after the program is terminated, and is stored to the remaining part of the field. The field includes an activation ID(10), a function ID(20), starting/keeping times(30,40) of the activation ID, initial child/sibling function activation IDs(50,60) of the activation ID, a next activation ID(70), and a parent function activation ID(80) of the activation ID.
    • 提供了一种使用关系数据库跟踪程序的方法,通过跟踪功能调用,搜索程序路径,解决具有父功能的瓶颈并调用特定时间点的堆栈信息来提高程序性能。 在程序执行期间从程序中提取用于跟踪程序的第一跟踪数据,并将其存储到关系数据库的一部分。 通过在程序终止后从存储的函数调用的第一跟踪数据中追踪字段的剩余部分来提取第二跟踪数据,并存储到字段的剩余部分。 该字段包括激活ID的激活ID(10),功能ID(20),启动ID的启动/保持时间(30,40),激活ID的初始子/同级功能激活ID(50,60),下一个 激活ID(70)和激活ID的父功能激活ID(80)。

    • A data storage system including a buffer for a non-volatile memory and the buffer for a disk, and a data access method thereof are provided to reduce a data access time for data stored in the non-volatile memory and the disk by using a non-volatile memory buffer and a disk buffer. A data storage system is equipped with a non-volatile memory(170), a disk(180), a non-volatile memory buffer(130), and a disk buffer(140). The non-volatile memory buffer stores a part of areas of the non-volatile memory between a host(110) and the non-volatile memory. The disk buffer stores a part of disks between the host and the disk. The data storage system checks a device corresponding to an access address received from the host in order of the non-volatile memory buffer, the non-volatile memory, the disk buffer, and the disk. The data corresponding to the access address is returned to the host if the access address is found.
    • 提供了包括用于非易失性存储器的缓冲器和用于盘的缓冲器的数据存储系统及其数据访问方法,以通过使用非易失性存储器来减少存储在非易失性存储器和盘中的数据的数据访问时间 - 易失性内存缓冲区和磁盘缓冲区。 数据存储系统配备有非易失性存储器(170),磁盘(180),非易失性存储器缓冲器(130)和磁盘缓冲器(140)。 非易失性存储器缓冲器在主机(110)和非易失性存储器之间存储非易失性存储器的一部分区域。 磁盘缓冲区将一部分磁盘存储在主机和磁盘之间。 数据存储系统根据非易失性存储器缓冲器,非易失性存储器,磁盘缓冲器和磁盘的顺序检查与从主机接收的访问地址相对应的设备。 如果发现访问地址,则与访问地址对应的数据将返回主机。

    • A method for dynamically scaling voltage of a CPU by using a workload estimator and a recording medium storing a program thereof are provided to operate the CPU in low power consumption by using a workload estimator after making workload profiling by a code segment unit . A voltage setting point is set to each code segment of a program(S210). Changes of the workloads of each code segment are measured based on data changed in each measurement(S220). A plurality of combinations respectively equipped with the voltage setting points are selected(S230). The workload estimators corresponding to each voltage setting point of the selected combinations are calculated based on the measured changes of the workload(S240). An optimal combination having the smallest power consumption of the CPU is selected based on the workload estimators(S260).
