Publication number: 20080172551Abstract: To verify an addition-function of a floating-point adder-subtractor in a processor, parameters such as the number of verification patterns of a verification program are set, a floating-point addition instruction to be verified is created, and operands used for this addition are created at random. The floating-point addition instruction thus created is emulated only by a fixed-point instruction and processed only by using the fixed-point execution element, thereby creating an expectation value. The floating-point addition instruction is computed by using the floating-point adder-subtractor to be verified, and the created expectation value is compared with the operation result. If they do not correspond to each other, the set number of operation patterns is checked. If the number has reached a prescribed value, the operation verification is terminated in the normal manner.Type: ApplicationFiled: February 8, 2008Publication date: July 17, 2008Applicant: FUJITSU LIMITEDInventors: Hideo YAMASHITA, Ryuji Kan

Patent number: 5838601Abstract: An arithmetic processing method and arithmetic processing device each which can reduce the number of logical stages needed to obtain the final arithmetic result, thus executing an arithmetic process such as a floating-point multiplication at high speed to reduce the arithmetic process time. According to the arithmetic processing method and arithmetic processing device, the possibility that an arithmetic exception occurs in the arithmetic result obtained through an arithmetic process is judged in the middle of the arithmetic process of the dedicated arithmetic processing unit. Transmitting an arithmetic end signal to the instruction control unit is inhibited when it is judged that there is a possibility; the arithmetic process with the possibility is executed by means of another arithmetic unit different from the dedicated arithmetic unit. Thereafter the arithmetic end signal regarding the arithmetic process is transmitted to the instruction control unit.Type: GrantFiled: July 2, 1996Date of Patent: November 17, 1998Assignee: Fujitsu LimitedInventors: Hideo Yamashita, Yuji Yoshida
