Patent number: 10302721Abstract: Procedure instruction sequences (P1˜PN) in an instruction sequence (for example, an instruction sequence for an NMR spectrometer) are generated in a precedential manner, and transferred to a procedure storage area on a transmission and reception unit in a precedential manner. After the precedential transfer, a remaining portion of the instruction sequence (streaming instruction sequence (SM1, . . . )) is sequentially generated in predetermined units from the beginning, and sequentially transferred to a FIFO area on the transmission and reception unit. A sequencer refers to the streaming instruction sequence, executes the instruction, and refers to a procedure instruction sequence on the procedure storage area.Type: GrantFiled: July 22, 2015Date of Patent: May 28, 2019Assignee: JEOL Ltd.Inventors: Kenichi Hachitani, Kenya Izumi, Yukio Nishimura, Takayuki Suzuki
