Provided is a reconfigurable processor that may process a first type of operation in first mode using a first group of functional units, and process a second type of operation in second mode using a second group of functional units. The reconfigurable processor may selectively supply power to either the first group or the second group, in response to a mode-switch signal or a mode-switch instruction.

Reconfigurable processor using power gating, compiler and compiling method thereof

An apparatus and method for controlling a low-voltage memory in a mobile communication system are provided. The apparatus includes a memory for storing data including at least one error caused by a low-voltage, and an error correction unit for identifying whether the at least one error exists in the memory according to a first bit set in a local buffer of an error correction code storage, for comparing location information on the error data read from the memory and location information on error data of at least one protection set in the local buffer of the error correction code storage when it is determined that the at least one error exists in the memory, for generating an error correction code as a result of the comparison, and for correcting the error data of the memory according to the error correction code.

Apparatus and method for controlling memory in mobile communication system

A method of controlling a non-volatile memory device includes comparing the number of banks that are in operating states with a threshold value. If the number of the banks is smaller than the threshold value, data stored in a standby bank is read. If there is no bank having data to be read, a standby bank is programmed. If the number of the banks is equal to or greater than the threshold value or if the reading or the programming is performed, it is determined whether there is a reading or programming command to be performed. If there is the reading or programming command to be performed, the process is repeated from the comparing step. The programming may include programming of a most significant bit (MSB) page or a least significant bit (LSB) page.

Method of controlling non-volatile memory device

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.

Program trace method using a relational database

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.
