摘要: An apparatus and method capable of reducing idle resources in a multicore device and improving the use of available resources in the multicore device are provided. The apparatus includes a static scheduling unit configured to generate one or more task groups, and to allocate the task groups to virtual cores by dividing or combining the tasks included in the task groups based on the execution time estimates of the task groups. The apparatus also includes a dynamic scheduling unit configured to map the virtual cores to physical cores.

摘要: Provided is a Direct Memory Access (DMA) controller which provides a function of searching for a specific pattern from data being transmitted during DMA transmission. The DMA controller stores at least one pattern value. The DMA controller compares data being transmitted to a pattern value while transmitting the data using a DMA method, and generates, in response to data matching the pattern value being detected, a signal indicating that the data matching the pattern value has been detected. The DMA controller stores an address of the data matching the pattern value in response to the generated signal.
