Abstract: Execution circuitry executes, in response to an instruction referencing a given source register of a register file, a data processing operation on pre-processed operand data obtained after a pre-processing action has been performed using stored operand data from the given source register of the register file. A buffer separate from the register file stores pre-processed operand data corresponding to a subset of registers. Register reuse detection circuitry detects a register reuse opportunity for a subsequent instruction referencing a reused source register also referenced by a previous instruction for which pre-processed operand data corresponding to the reused source register was written to the buffer, when it is guaranteed that no intervening instruction will cause a write to the reused source register.

Abstract: Methods, systems, and devices that support a dynamic screen refresh rate are described. An electronic device may dynamically (e.g., autonomously, while operating) adjust the rate at which a screen is refreshed, such as to balance considerations such as user experience and power consumption by the electronic device. For example, the electronic device may use an increased refresh rate when executing applications for which user experience is enhanced by a higher refresh rate and may use a decreased refresh rate when executing other applications. As another example, the electronic device may use different refresh rates while executing different portions of the same application, as some aspects of an application (e.g., more intense portions of a video game) may benefit more than others from a higher refresh rate. The electronic device may also account of rother factors, such as battery level, when setting or adjusting the refresh rate of the screen.
