Patent number: 6907480Abstract: A data processing system enables faster exchange of data between data processing units having a CPU, and simplifies the writing of a data exchange program for the data processing units. A data processing apparatus 3 has a communication unit 4 with a first storage unit 31 and a second storage unit 32. The first storage unit 31 is used for sending data from the first data processing unit 1 to the second data processing unit 2. The second storage unit 32 is used for sending data from the second data processing unit 2 to the first data processing unit 1. Data can therefore be asynchronously exchanged between the data processing units without coordinating control of CPU operations in the data processing units, and control of data communication between the data processing units is simplified.Type: GrantFiled: March 28, 2002Date of Patent: June 14, 2005Assignee: Seiko Epson CorporationInventors: Toshiki Takei, Hiroaki Kasuga

Patent number: 6847180Abstract: Control data is efficiently serially transferred to a drive device for driving a motor without involving the CPU. Data buffers are allocated at specific memory addresses. An address decoder decodes a memory address output to the address bus and applies a write enable signal to the corresponding data buffer to write data to that data buffer by DMA transfer. When data is written to a data buffer, a sequencer circuit compiles control data, based on data in that data buffers, in a shift register, and serially transfers the control data one bit at a time on a serial transfer line synchronized to a clock.Type: GrantFiled: May 9, 2003Date of Patent: January 25, 2005Assignee: Seiko Epson CorporationInventor: Toshiki Takei
