US Patent 7680962 Stream processor and information processing apparatus

An array type processor comprises a data path unit to execute processing, and a state management unit to control the state of the data path unit in accordance with a command that specifies processing on the data. An input DMA circuit reads from a memory information and data to be processed including a command corresponding to the data. The input DMA circuit first transfers the command to the state management unit, and then transfers the data to be processed to the data path unit.
