PROBLEM TO BE SOLVED: To realize a high-speed development process of compressed data and a high-speed data transfer to a liquid ejecting head at low cost, so that the liquid ejection executing speed of a liquid ejecting apparatus is considerably increased compare with conventional cases at low cost. SOLUTION: A data transferring apparatus 10 is provided with an ASIC (Application Specific Integrated Circuit) 4. The ASIC 4 incorporates an interface unit 27, a head controlling unit 33, a receiving buffer unit 42, and a DECU 41, and each of the above described units is connected to a system bus SB so that data transfer can be performed. The DECU 41 incorporates a development processing controller 412 having a decode circuit 28 for subjecting compressed record data to hardware development and a line buffer 281 for storing developed record data. The DECU 41 and the head controlling unit 33 are connected by an internal bus IB such that data transfer can be performed. COPYRIGHT: (C)2005,JPO&NCIPI
