摘要： A power converter having a switched capacitor buck/boost operation has first and second switches coupled to a first switching node, third and fourth switches coupled to a second switching node, a capacitor coupled between the first and second switching nodes, and an inductor coupled to the first switching node. A switch controller controls the switches to operate in voltage step-down mode and voltage step-up mode depending on a difference between converter output voltage VOUT and converter input voltage VIN. In a buck-optimized topology operating in a step-down mode, an output current flowing through the first switching node flows through only one switch at a given time. In a boost-optimized topology operating in a step-up mode, an output current flowing through the first switching node flows through only one switch at a given time. As a result, a more compact and efficient power converter may be realized at lower cost.

摘要： In general, this disclosure describes techniques for selecting a memory channel in a multi-channel memory system for storing data, so that usage of the memory channels is well-balanced. A request to write data to a logical memory address of a memory system may be received. The logical memory address may include a logical page number and a page offset, where the logical page number maps to a physical page number and the logical memory address maps to a physical memory address. A memory unit out of a plurality of memory units in the memory system may be determined by performing a logical operation on one or more bits of the page offset and one or more bits of the physical page number. The data may be written to a physical memory address in the determined memory unit in the memory system.

摘要： A system and method for detecting errors in high-speed asymmetric interfaces are described. Embodiments include transmitting digital data between a first system component and a second system component over a bidirectional interface, wherein the first component is significantly more intelligent than the second component. The first component controls many operations of the second component, including receiving a signature from the second component over an existing line of the interface. The signature received is compared to a signature stored by the first component. Both signatures correspond to a transaction over the interface. Based on the comparison, the first component determines whether the transaction was successful, and directs the second component as necessary.
