Abstract: Provided is a modulo scheduling method. The modulo scheduling method includes conducting a search, based on a data dependency graph of a loop, for a recurrence in which a sum of iteration distances between command nodes is less than a predetermined critical value; and determining a processing order of the recurrence.

Abstract: An electronic device may comprise: a first memory for storing first data at a designated rate; a first processor connected to the first memory and configured to divide the first data into multiple second data, each having a size smaller than the size of the first data; a second memory for storing at least some of the multiple second data at a rate faster than the designated rate; a second processor connected to the second memory and configured to process the at least some of the multiple second data; and a DMA control module, connected to the second processor, for transmitting/receiving data between the first memory and the second memory, wherein the DMA control module is configured to: at least on the basis of a processing command for the multiple second data which is transmitted from the first processor to the second processor, receive, from the first memory, the at least some of the multiple small-sized second data divided from the first data; transmit the at least some of the multiple second data to the second processor; and transmit, to the first memory, third data processed by the second processor by using the at least some of the multiple second data.

Abstract: An apparatus for detecting a source code error location in a mixed-mode program is disclosed. The apparatus may include a compiler, a mapping table generator, a simulator, a comparison data generator and an error location detector. The apparatus extracts low-level data while simulating a verification program and while simulating a reference program. The low-level data is mapped to mapping tables for a verification program and a reference program, and by comparing the tables it is determined if there is an error in the mixed-mode program and if so, where.
