Patent number: 7788469Abstract: A hardware accelerator is used to execute a floating-point byte-code in an information processing device. For a floating-point byte-code, a byte-code accelerator BCA feeds an instruction stream for using a FPU to a CPU. When the FPU is used, first the data is transferred to the FPU register from a general-purpose register, and then an FPU operation is performed. For data, such as a denormalized number, that cannot be processed by the FPU, in order to call a floating-point math library of software, the processing of the BCA is completed and the processing moves to processing by software. In order to realize this, data on a data transfer bus from the CPU to the FPU is snooped by the hardware accelerator, and a cancel request is signaled to the CPU to inhibit execution of the FPU operation when corresponding data is detected in a data checking part.Type: GrantFiled: July 6, 2004Date of Patent: August 31, 2010Assignee: Renesas Technology Corp.Inventors: Tetsuya Yamada, Naohiko Irie, Takahiro Irita, Masayuki Kabasawa
