Abstract:
A method of generating a virtual address in a data processing system controller includes receiving and analyzing attribute information which indicates whether user intervention is possible for allocating a memory buffer for storing image data; enabling one of a first virtual address generator or a second virtual address generator based on an analysis result; and generating the virtual address of a data transaction using the enabled virtual address generator.
Abstract:
A coherent interconnect is provided. The coherent interconnect includes a snoop filter and a circuit that receives a write request, strobe bits, and write data from a central processing unit (CPU); generates a snoop filter request based on the write request; and transmits, at substantially the same time, the snoop filter request to the snoop filter and the write request, the strobe bits, and the write data to a memory controller.

Abstract:
A system on chip (SoC) and a method of operating the same are provided. The SoC includes a central processing unit (CPU) controlling a memory operation and a display operation on a current frame of an image based on generation of the image and an interrupt signal; an image generator requesting data of the current frame from a memory according to control of the CPU; a UD unit determining whether the current frame is updated, detecting whether an update region is a partial frame based on virtual addresses included in a request of the image generator, and outputting the interrupt signal corresponding to the update region to the CPU; a memory controller storing the update region in the memory according to the control of the CPU; and a display controller accessing the memory and outputting the update region to a display device according to the control of the CPU.
