摘要： One multiplier 13 operated at a normalized frequency 4 is provided to multiply the elements of DCT transformation coefficients and the elements of input data, and the multiplication results are added by a cumulative adder 15 to determine cumulative addition results corresponding to the sum (x0+x7) and the difference (x0−x7) of a pair of elements (x0, x7) of data to be outputted from a one-dimensional DCT operation circuit 1. The paired cumulative addition results are added and subtracted by an adder 17 and a subtracter 18, respectively, to determine the elements (x0, x7). The operations are performed specific times the number of which is one half of the number of elements of a column of the matrix of the input data to determine the elements of a column of the matrix of the output data and are performed specific times the number of which is equal to the number of elements of a row of the matrix or the input data to determine all the elements of the matrix of the output data. As a result, the scale of the DCT operation circuit is reduced, thereby reducing the power consumption.

摘要： A bus arbitration apparatus for an image processing processor is operable such that when a channel having a high necessity of a real-time processing operation issues a bus use request, a bus use permission is not given to another channel having a low necessity of a real-time processing operation. The bus arbitrator of the data includes a timer for counting down use permission time with respect to the channel having the high necessity of the real-time processing operation, and a register for the channel having the low necessity of the real-time processing operation. A value larger than a maximum value of the timer is set to the value of the register. In the bus arbitration, the value of the register is compared with that of the timer, and then the bus use permission is given to a channel having the small value.

摘要： The present invention provides a technology that is implemented in a motion compensation image coding device or a coding method and intended to code motion picture data in real time by performing a decreased number of arithmetic operations so as to determine a motion vector. In motion compensation image coding, macroblocks and sub-blocks into which each of the macroblocks is divided are searched for a motion vector with integer pixel precision. Based on the results of the search, a shape of a block that should be searched for a motion vector with decimal pixel precision is determined as a shape mode. The block of the shape mode is searched for a motion vector with decimal pixel precision, whereby a motion vector needed to produce predictive image data is determined.
