Abstract: The invention relates to apparatuses and methods for enhancing call quality in wireless earbuds. A first wireless earbud includes a first speaker and a first downlink speech process path, and a second wireless earbud includes a second speaker and a second downlink speech process path. The first and the second downlink speech process paths receive the same mono speech data from a mobile phone, and process the mono speech data to generate first and second analog signals, respectively, so that the first and the second speakers play the first and second analog signals, respectively. An inverter is disposed on the first downlink speech process path to generate the inverted digital data or analog signal from received digital data or analog signal corresponding to the mono speech data, but no inverter is disposed on the second downlink speech process path.

Abstract: An electronic device and associated method is provided. The electronic device includes: a plurality of subsystems including hardware resources; a battery coupled to the plurality of subsystems; and a processing unit, configured to allocate a virtual battery from the battery for each subsystem, wherein each virtual battery has a defined power budget from the battery.

Abstract: A low-power memory access method and associated apparatus are provided. The apparatus includes a memory controller and a processing unit. The memory controller is coupled to a first memory and a second memory, and includes: a memory management circuit, for allocating physical memory addresses of the first memory and the second memory and controlling access of the first memory and the second memory; and a direct-memory-access (DMA) controller. The processing unit is for accessing the first memory and the second memory via the memory controller. When the apparatus is in an active mode, the memory management circuit copies a portion of data stored in the second memory to the first memory for use by the processing unit, and records dirty data information when the portion of data in the first memory differs from that in the second memory.

Abstract: For an electronic apparatus with a sleep mode and an operation mode, an erasing command is issued to a memory controller that controls a non-volatile memory device before the electronic apparatus is entering the sleeping mode. Preferably, an estimated sleeping time is compared with a predetermined threshold for determining whether to activate erase operations to release space from the non-volatile memory device. Further, when the electronic apparatus returns from the sleep mode to the operation mode, the erase operations are checked whether they are complete. If the erase operations are not completed, another erase command is issued to the memory controller next time when the electronic apparatus is going to the sleep mode again.
