Abstract: An Android-based system for touch input handling is provided. The system includes an interactive hardware and an application processor. The interactive hardware includes a display panel and a touch panel that runs a touch firmware. The application processor is coupled to the interactive hardware, and runs an application program and a touch driver. The application processor further converts a hardware synchronization signal of the display panel into a software synchronization signal, and generates an application synchronization signal based on the software synchronization signal. Additionally, the application processor further generates an input synchronization signal that is synchronized with the application synchronization signal. The expiration of the input synchronization signal triggers the touch firmware to collect the touch event and propagate the touch event up to the application program through the touch driver.

Abstract: Embodiments protect against memory-based side-channel attacks by efficiently shuffling data. In an example implementation, in response to a data access request by an encryption methodology regarding a first data element from amongst a plurality of data elements stored in memory, a storage address of a second data element of the plurality is determined. This storage address is determined using (i) an address of the first data element in the memory, (ii) a permutation function, and (iii) a random number. In turn, the first data element is stored at the determined storage address of the second data element and the second data element is stored at the address of the first data element. In this way, embodiments protect encryption methodologies from memory-based side-channel attacks.

Abstract: Examples pertaining to improvement on user equipment (UE) uplink latency in wireless communications are described. When an apparatus is in a special mode, a processor of the apparatus transmits to a network a request for permission to perform an uplink (UL) transmission for a plurality of times.
