摘要

The present invention provides a relatively fast a size almost similar hardware floating point operations while the reconfiguration of the conventional array structure can be carried out, low-power and price reconstruction array processor having a high performance ratio characteristic (Reconfigurable Array Processor), and provides a multimedia platform, including the processor. The reconstruction array processor at least two integer operation processing elements (processing element: PE) floating point unit made by combining the (Floating-Point Unit: FPU) -PE are arranged a plurality of the PE array (array); Context for controlling the communication of data between each row or column of PE and PE the PE array operations (context) which is stored the configuration cache (Configurable Cache); And the PE array, the cache memory of a frame buffer to store the intermediate result of (Frame buffer);., And include, the FPU-PE using a floating-point (floating point) operations can be performed
