Title:
INFORMATION TRANSFER DEVICE AND INFORMATION TRANSFER METHOD OF INFORMATION TRANSFER DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/093475
Kind Code:
A1
Abstract:
A bus interface (10) comprises a bypass buffer (21) which temporarily stores data. If the bus interface (10) receives a read request from a system controller (30), the bus interface (10) acquires read-request data from a register group (25). At such time, if the bus interface (10) has not been able to acquire the data before a predetermined amount of time has elapsed from receiving the read request, the bus interface (10) notifies the system controller (30) that transmission of the data has failed and stores subsequently acquired data in the bypass buffer (21). Thereafter, if the bus interface (10) has again not been able to acquire the data before a predetermined amount of time has elapsed from receiving a read retry request for the data for which transmission has failed, the bus interface (10) transmits the data stored in the bypass buffer (21) to the system controller (30).
