Abstract
An information processing device includes a first package including a first arithmetic circuit, first cache memory and a transmitting circuit, as well as a second package including a second arithmetic circuit, second cache memory and a receiving circuit. The first arithmetic circuit is configured to provide transfer data to the first cache memory that is destined for the second cache memory. The transmitting circuit is configured to transmit to the receiving circuit an indication of a data transfer of the transfer data and to restrict use of the first cache memory for data other than the transfer data during the data transfer. The receiving circuit is configured to receive the indication of the data transfer, to acquire the transfer data stored in the first cache memory and to store the acquired transfer data in the second cache memory.
