An apparatus for and method of processing a vertex in relation to 3 dimensional (3D) graphics pipeline are provided. According to the method, while a processor processes vertex data in units of batches, vertex data corresponding to a batch to be processed next is extracted and temporarily stored in a buffer independently of the processor. If the processor finishes processing of the current batch, the batch stored in the buffer is output so that the processor can immediately process the batch.

Provided are a method and apparatus for avoiding bank conflict. A first instruction that is one of access instructions that are predicted to cause the bank conflict is replaced with a second instruction by changing an execute timing of the first instruction to a timing prior to the execute timing of the first instruction so as for the access instructions not to cause the bank conflict. Next, a load/store unit that is scheduled to access the bank according to the first instruction accesses the bank and reads out a data from the bank at an execute timing of the second instruction, and after that, the load/store unit is allowed to be inputted the read data at the execute timing of the first instruction. Accordingly, although the access instructions that are predicted to cause the bank conflict are allocated to the load/store units, the bank conflict can be prevented, so that it is possible to avoid deterioration in performance due the occurrence of the bank conflict.

An image interpolation method interpolating image information of a point in a space constructed by a plurality of planes. According to the method, a reliable interpolated value can be rapidly obtained by searching for the nearest plane to the point, obtaining information about a plane facing the nearest plane using image information of one or more vertices of the plane facing the nearest plane, and interpolating the image information of the point using the image information of the one or more vertices of the nearest plane and the obtained information about the plane facing the nearest plane.

Provided is a method for converting a first image signal expressed in a first color space into a second image signal expressed in a second color space on a subword parallelism basis. The method includes determining a first image parameter of a second image signal matrix as a function calculated by multiplying conversion coefficients of a first row constituting an image conversion matrix by image parameters constituting a first image signal matrix; determining a second image parameter of the second image signal matrix as a function expressed by at least one of image parameters constituting the first image signal matrix and the determined first image parameter of the second image signal matrix; determining a third image parameter of the second image signal matrix as a function expressed by at least one image parameter unused for determining the second image parameter of the second image signal matrix among the image parameters constituting the first image signal matrix, and by the determined first image parameter of the second image signal matrix; and finally calculating the second image signal matrix by shifting the determined image parameters constituting the second image signal matrix by a predetermined number of bits.
