摘要： A clamping system for clamping a video signal, wherein the clamping system uses a charge-pump unit in company with a digital clamping controller to clamp the potential of the video signal, prior to the video signal being input to a programmable gain amplifier and an A/D converter, so as to reach a desired level. The charge-pump unit provides two charge-pump circuits, wherein one charge-pump circuit supplies a strong burst to boost the potential of the video signal while the video signal is below a threshold value. Otherwise, the other charge-pump circuit supplies a weak burst to fine tune the potential of the video signal when the video signal has reached the threshold value.

摘要： The multi-mode Multiplier-And-Accumulator of the present invention is used with the double-precision Complex-Valued Multiplier-And Accumulator as a main configuration, and the different precisions and digital modes make it more flexible, compared to the traditional real number Multiplier-And-Accumulator. In addition, it does not have a data alignment problem which occurs in the traditional application of different precision Subword Parallel processors. This kind of Multiplier-And-Accumulator takes a double-precision Complex-Valued Multiplier-And- Accumulator as the main configuration, with four double-precision real-valued multipliers and several groups of accumulators to assist in different modes ofoperation. Each double-precision real- valued multiplier can be segmented into four single-precision multipliers, and then double-precision multiplier products are obtained by means of displacement addition. If two real numbers which are continuous in time sequence are taken as the real number input and imaginary number input for the original complex-valued multipliers, the accumulated products include not only the present output accumulated product summation but also the output accumulated product summation of the previous time and the next time.

摘要： A sorted QR decomposition method used in a detection of a multiple input multiple output (MIMO) communication system is provided. First, whether a sorting-stop parameter of a channel transformation matrix of the MIMO communication system is greater than or equal to a sorting-stop threshold is determined. Then, whether energy of elements in a leftmost column within a process area of the channel transformation matrix is completely transferred to a top element in the leftmost column is determined. If the energy of the elements in the leftmost column within the process area is not yet completely transferred to the top element in the leftmost column, a unit process area of a process unit set is expanded.
