Patent number: 7594099Abstract: A processor according to the present invention includes a decoding unit 20, an operation unit 40 and others. When the decoding unit 20 decodes Instruction vcchk, the operation unit 40 and the like judges whether vector condition flags VC0˜VC3 (110) of a condition flag register (CFR) 32 are all zero or not, and (i) sets condition flags C4 and C5 of the condition flag register (CFR) 32 to 1 and 0, respectively, when all of the vector condition flags VC0˜VC3 are zero, and (ii) sets the condition flags C4 and C5 to 0 and 1, respectively, when not all the vector condition flags are zero. Then, the vector condition flags VC0˜VC3 are stored in the condition flags C0˜C3.Type: GrantFiled: August 31, 2007Date of Patent: September 22, 2009Assignee: Panasonic CorporationInventors: Tetsuya Tanaka, Hazuki Okabayashi, Taketo Heishi, Hajime Ogawa, Tsuneyuki Suzuki, Tokuzo Kiyohara, Takeshi Tanaka, Hideshi Nishida, Masaki Maeda

Patent number: 7305499Abstract: The present invention provides a DMA transfer controller includes: a transfer parameter storing unit for storing a bus occupation time value and transfer parameters of one set or a plurality of sets of DMA transfers for each of a plurality of logical processors; a data transfer performing unit for performing the DMA transfer on the basis of the DMA transfer parameters; a control unit for controlling the receive and transmit of the DMA transfer parameters and the start and the interruption of the DMA transfers; and a time measuring unit for starting to measure bus occupation elapse time when a first DMA transfer is started for each of the logical processors. When the bus occupation elapse time reaches the bus occupation time value, the control unit interrupts the DMA transfer that is currently performed to start the DMA transfers based on the transfer parameters related to the logical processors of a prescribed sequence.Type: GrantFiled: July 29, 2004Date of Patent: December 4, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Akihiro Furuta, Nobuo Higaki, Tetsuya Tanaka, Tsuneyuki Suzuki
