  • Patent number: 9141208
    Abstract: A method of segmenting multiple touches in a touch sensor system is disclosed. The method includes setting a point node by selecting a valid node of a touch sensor panel from among valid nodes having touch data equal to or greater than a threshold value of a touch sensor panel; determining one or more candidate labels for the point node by searching for adjacent nodes around the point node; and when there are two or more candidate labels for the point node, labeling the point node by selecting a label of a label group that has the highest group similarity with the point node and that is from among label groups of the two or more candidate labels, and by assigning the selected label to the point node.

  • Patent number: 8984237
    Abstract: A multi-processor system includes a first processor, a second processor communicable with the first processor, a first non-volatile memory for storing first codes and second codes to respectively boot the first and second processors, the first memory communicable with the first processor, a second volatile memory designated for the first processor, a third volatile memory designated for the second processor, and a fourth volatile memory shared by the first and second processors.

  • Patent number: 8711652
    Abstract: A plurality of masters arbitrate for access to a shared memory device, such as a SDRAM (synchronous dynamic random access memory), amongst themselves using software and arbitration interfaces. The masters generate additional commands upon arbitration, such as MRS and PALL commands, for prevention of collision of commands, refresh starvation, and/or a missing pre-charge operation in the shared memory device.

  • Patent number: 8209527
    Abstract: A booting method of a digital processing having a first processor and a second processor is provided. An interface between the first processor and the outside is stopped. A second processor program code is transmitted to a second memory from a first memory. A second stage loader (SSL) for the first processor is transmitted to a buffer of the second processor from the first memory. A first processor program code is transmitted to the second memory from the first memory under the control of the second processor and an interface between the first processor and the outside is resumed. The first processor program code is downloaded fast into the second memory to decrease booting time of the digital processing system.
