Abstract: The present disclosure relates to power conversion, and more particularly, to systems, methods, apparatuses, and integrated circuits for power conversion with improved regulator control. In one embodiment, a power converter system is disclosed, comprising: a power conversion circuit; a linear regulator; a first switching device electrically coupled between an output of the power conversion circuit and an output of the linear regulator; and a control circuitry electrically coupled to the first switching device. In this power conversion circuit, after a voltage at the output of the power conversion circuit exceeds a reference voltage, the control circuitry is configured to discharge an output capacitance of the linear regulator until a voltage at the output of the linear regulator is substantially the same as the voltage at the output of the power conversion circuit.

Abstract: A method of storing an array of digital data into a memory. The memory includes a plurality of memory pages, and each memory page has a first memory section and a second memory section. The method includes a first step of dividing the array of digital data into a plurality of block units, while each of the block units has a plurality of odd rows and a plurality of even rows, and each of the odd rows and the even rows has at least one byte. The method further includes a second step of storing subsequent odd rows of at least one of the block units into consecutive storage locations in the first memory section, and storing subsequent even rows of at least one of the block units into consecutive storage locations in the second memory section. In this way, the memory bandwidth can be used more efficiently.

Abstract: A method of storing an array of digital data, for example, pixel data of a picture in a video bit stream, into a memory. In one embodiment, the memory includes a plurality of memory pages, and each memory page has a first memory section and a second memory section. The method includes a first step of dividing the array of digital data into a plurality of block units, while each of the block units has a plurality of odd rows and a plurality of even rows, and each of the odd rows and the even rows has at least one byte. The method further includes a second step of storing subsequent odd rows of at least one of the block units into consecutive storage locations in the first memory section, and storing subsequent even rows of at least one of the block units into consecutive storage locations in the second memory section.

Abstract: A memory access method for video decoding is provided. More particularly, a method of storing pixel data of a reference picture and retrieving a prediction block of the reference picture from a memory is provided. The memory is divided into several pages. The reference picture consists of a top field and a bottom field, and is divided into several macroblocks. Each macroblock has a corresponding portion of the top field and the bottom field. The method includes the steps of: dividing each page into a top-section having one or more consecutive addressing area and a bottom-section having one or more consecutive addressing areas; storing the corresponding top field and corresponding bottom field of the macroblocks into the top-sections and bottom-sections, respectively; and then retrieving the pixel data of the prediction block stored in the memory in a page-by-page manner.
