Abstract: A control method in use of a flyback power converter is disclosed to provide an operation power source supplying power to a power controller controlling a main power switch. The flyback power converter has a transformer with a primary winding and an auxiliary winding. The main power switch and the primary winding are connected in series. A chopper switch and a buffer inductor are connected in series between the auxiliary winding and the power controller. The power controller turns ON the main power switch for an ON time to energize the transformer, and turns ON the chopper switch for at least a time period during the ON time, so that during the time period the buffer inductor conducts an induced current flowing from the auxiliary winding and through the chopper switch, to build up the operation power source.

Abstract: For a given application, increasing the size of a cache is beneficial up to a certain point and the number of hits does not increase significantly with a greater cache size. This disclosure provides a method to determine a miss ratio curve, for a cache having data blocks with a time-to-live. A hashed value of a data block's key address can be used to generate a 2D HLL counter for storing expiry times of the data blocks. The 2D HLL counter can be converted to a 1D array, from which a stack distance can be calculated. A frequency distribution of stack distances can then be converted into a miss ratio curve, from which an appropriate cache size can be selected.

Abstract: Example methods and apparatus for data access are described. In one example, a memory expansion card receives a first data access request generated by a computing device based on an internal bus protocol. Then, the memory expansion card performs protocol conversion on the first data access request to obtain a second data access request in an external bus protocol format, where the external bus protocol includes a bus protocol for accessing external memory space of the computing device. Further, the memory expansion card accesses the external memory space based on the second data access request. The memory expansion card shields a difference between the bus protocols, and provides internal memory space for the computing device.
