Claim Text:
1. A data processing device comprising: a buffer that temporarily stores data; a processor element that receives the data from the buffer to process it; a congestion determinator that determines a congestion level of a bus in the processor element; and a buffer accumulation suppressor that suppresses, according to said congestion level determination of the congestion determinator, an increase in a data amount stored in the buffer, wherein the processor element comprises wherein when data transmission from the buffer to the processor element occurs, if the data input unit cannot receive data from the buffer due to congestion of the bus, the data input unit sends to the buffer a retransmission request requesting to resend the non-received data, wherein the congestion determinator determines the congestion level of the bus based on whether a number of the retransmission requests that have occurred within a predetermined duration exceeds a predetermined retry counter upper limit, and wherein if the congestion determinator determines that the number of the retransmission requests that have occurred within the predetermined duration exceeds the predetermined retry counter upper limit, the buffer accumulation suppressor suppresses the increase in the data amount stored in the buffer.
