Abstract
An information processing apparatus includes a first bus interface to receive first data transferred in a pixel-parallel transfer mode, a second bus interface to receive second data transferred in a line-parallel transfer mode, a selector to select one of the first data transferred in the pixel-parallel transfer mode and the second data transferred in the line-parallel transfer mode, as input data, a transfer switching circuit to switch between the line-parallel transfer mode and the pixel-parallel transfer mode to process the input data according to the switched transfer mode.
Claims19
An information processing apparatus comprising:
- a first bus interface to receive first data transferred in a pixel-parallel transfer mode, wherein a plurality of pixels belonging to a same line of the first data are transferred in parallel for a plurality of lanes of data;
- a second bus interface to receive second data transferred in a line-parallel transfer mode, wherein a plurality of lines of the second data having a same number of the lanes are transferred in parallel;
- a selector to select either the first data transferred in the pixel-parallel transfer mode or the second data transferred in the line-parallel transfer mode, as input data;
- and
- a transfer switching circuit to process the input data according to the selected transfer mode, wherein a line is a direction of pixel arrangement along a vertical axis and a lane is a direction of pixel arrangement along a horizontal axis.
An information processing apparatus comprising:
- first means for receiving first data transferred in a pixel-parallel transfer mode, wherein a plurality of pixels belonging to a same line of the first data are transferred in parallel for a plurality of lanes of data;
- second means for receiving second data transferred in a line-parallel transfer mode, wherein a plurality of lines of the second data having a same number of the lanes are transferred in parallel;
- means for selecting either the first data transferred in the pixel-parallel transfer mode or the second data transferred in the line-parallel transfer mode, as input data;
- and
- means for processing the input data according to the selected transfer mode, wherein a line is a direction of pixel arrangement along a vertical axis and a lane is a direction of pixel arrangement along a horizontal axis.
A method of transferring data comprising:
- receiving, at a first bus interface, first data transferred in a pixel-parallel transfer mode, wherein a plurality of pixels belonging to a same line of the first data are transferred in parallel for a plurality of lanes of data;
- receiving, at a second bus interface, second data transferred in a line-parallel transfer mode, wherein a plurality of lines of the second data having a same number of the lanes are transferred in parallel;
- selecting either the first data transferred in the pixel-parallel transfer mode or the second data transferred in the line-parallel transfer mode, as input data;
- and
- processing the input data according to the selected transfer mode, wherein a line is a direction of pixel arrangement along a vertical axis and a lane is a direction of pixel arrangement along a horizontal axis.
