Abstract
A semiconductor device with an arithmetic processing function is provided. The semiconductor device includes a first circuit and a second circuit each having a function of performing one-dimensional discrete cosine transform. By directly inputting output data of the first circuit to the second circuit, two-dimensional discrete cosine transform can be performed immediately. A memory cell array included in the first circuit is divided into a plurality of memory blocks. In the case where a selection transistor is provided in the memory block, data processing can be performed in each memory block.
