Publication number: 20150095616Abstract: The present invention realizes an efficient superscalar instruction issue and low power consumption at an instruction set including instructions with prefixes. An instruction fetch unit is adopted which determines whether an instruction code is of a prefix code or an instruction code other than it, and outputs the result of determination and the 16-bit instruction code. Along with it, decoders each of which decodes the instruction code, based on the result of determination, and decoders each of which decodes the prefix code, are disposed separately. Further, a prefix is supplied to each decoder prior to a fixed-length instruction code like 16 bits modified with it. A fixed-length instruction code following the prefix code is supplied to each decoder of the same pipeline as the decoder for the prefix code.Type: ApplicationFiled: December 9, 2014Publication date: April 2, 2015Inventors: Hiroaki Nakaya, Yuki Kondoh, Makoto Ishikawa

Publication number: 20110238883Abstract: An information processing device is provided, in which a bit operation is performed without degradation in performance of a bus. An information processing device includes a CPU which fetches and executes an instruction, and a peripheral module which includes internally a register rewritable by the CPU, and is coupled to the CPU via a bus. The CPU has a function of issuing a bus command for commanding a bitwise write operation to the register comprised in the peripheral module, in order to execute a bit operation command fetched. When the bus command is issued, the peripheral module executes a bitwise write operation for the register. Since the CPU does not need to lock the bus after the bus command is issued, a bit operation can be performed without degradation in performance of the bus.Type: ApplicationFiled: August 4, 2009Publication date: September 29, 2011Inventors: Hiroaki Nakaya, Tetsuya Yamada, Naoki Kato

Patent number: 7995405Abstract: A semiconductor memory device having high integration, low power consumption and high operation speed. The memory device includes a sense amplifier circuit having plural pull-down circuits and a pull-up circuit. A transistor constituting one of the plural pull-down circuits has a larger constant than that of a transistor constituting the other pull-down circuits, for example, a channel length and a channel width. The pull-down circuit having the larger constant transistor is activated earlier than the other pull-down circuits and the pull-up circuit, which are activated to conduct reading. The data line and the earlier driven pull-down circuit are connected by an NMOS transistor and the NMOS transistor is activated or inactivated to control the activation or inactivation of the pull-down circuit.Type: GrantFiled: December 14, 2010Date of Patent: August 9, 2011Assignees: Hitachi, Ltd., Elpida Memory, Inc.Inventors: Satoru Akiyama, Tomonori Sekiguchi, Riichiro Takemura, Hiroaki Nakaya, Shinichi Miyatake, Yuko Watanabe

Patent number: 7973582Abstract: Disclosed is a timing control circuit which receives a first clock having a period T1 and a group of second clocks of L different phases (where L is a positive integer) spaced apart from each other at substantially equal intervals and which generates a fine timing signal delayed from the rising edge of the first clock by a delay td of approximately td=m·T1+n·(T2/L), where m and n are non-negative integers. The timing control circuit has a coarse delay circuit and a fine delay circuit. The coarse delay circuit counts the rising edges of the first clock after an activate signal is activated and generates a coarse timing signal delayed from the first clock by approximately m·T1. The fine delay circuit has a circuit which, after the activate signal is activated, detects a second clock, which has a rising edge that immediately follows the rising edge of the first clock, from among the group of L-phase second clocks.Type: GrantFiled: September 5, 2008Date of Patent: July 5, 2011Assignee: Elpida Memory, Inc.Inventors: Akira Ide, Yasuhiro Takai, Tomonori Sekiguchi, Riichiro Takemura, Satoru Akiyama, Hiroaki Nakaya

Patent number: 7843250Abstract: A substrate voltage control technique that prevents the operating speed from being decreased and suppresses a leakage current due to a lower threshold voltage with respect to a low voltage use. Since a center value of the threshold voltages is detected by plural replica MOS transistors, and a substrate voltage is controlled to control a center value of the threshold voltages, thereby making it possible to satisfy a lower limit of the operating speed and an upper limit of a leakage current of the entire chip. On the other hand, the substrate voltage is dynamically controlled during the operation of the chip, thereby making it possible to decrease the center value of the threshold voltages when the chip operates to improve the speed, and to increase the center value of the threshold voltages after the operation of the chip to reduce the leakage current of the entire chip.Type: GrantFiled: January 13, 2010Date of Patent: November 30, 2010Assignee: Hitachi, Ltd.Inventors: Hiroaki Nakaya, Satoru Akiyama, Tomonori Sekiguchi, Riichiro Takemura
