摘要：
A data transferring apparatus has an ASIC (Application Specific Integrated Circuit), and the ASIC incorporates an interface unit, a head controlling unit, a receiving buffer unit and a DECU, which are coupled to be capable of transferring data. The DECU incorporates a development processing controller having a decode circuit for performing hardware development on compressed recording data, and a line buffer storing developed recording data. The DECU and the head controlling unit are coupled by an internal bus IB in order to perform data transfer.
