Abstract
When free bank information representing that a bank is not used by a PE and outputted from a PE controller coincides with used bank information representing that a bank is used for data transfer and outputted from a bus controller, a memory controller controls LM-bankstoand a switching network so as to enable all communications. Therefore, data reading and data writing by the PE is performed in parallel with the data transfer with the outside, so that processing time of the PE can be reduced.
