  • Patent number: 8576643
    Abstract: A semiconductor integrated circuit has a central processing unit and a rewritable nonvolatile memory area disposed in an address space of the central processing unit. The nonvolatile memory area has a first nonvolatile memory area and a second nonvolatile memory area, which memorize information depending on the difference of threshold voltages. The first nonvolatile memory area has a maximum variation width of a threshold voltage for memorizing an information set larger than that of the second nonvolatile memory area. The first nonvolatile memory area can be prioritized to expedite a read speed of the memory information, and the second nonvolatile memory area can be prioritized to guarantee the number of times of rewrite operation of memory information.

  • Patent number: 8578135
    Abstract: A high-performance information processing technique permitting updating of an instruction buffer ready for effective prefetching to branch instructions and returning to the subroutine with a small volume of hardware is to be provided at low cost. It is an information processing apparatus equipped with a CPU, a memory, prefetch means and the like, wherein a prefetch address generator unit in the prefetch means decodes a branching series of instructions including at least one branched address calculating instruction and branching instruction to a branched address out of a current instruction buffer storing the series of instructions currently accessed by the CPU, and thereby looks ahead to the branching destination address. The information processing apparatus further comprises a RTS instruction buffer for storing a series of instructions of the return destinations of RTS instructions, and series of instructions stored in the current instruction buffer are saved into the RTS instruction buffer.

  • Patent number: 8130571
    Abstract: A semiconductor integrated circuit has a central processing unit and a rewritable nonvolatile memory area disposed In an address space of the central processing unit. The nonvolatile memory area has a first nonvolatile memory area and a second nonvolatile memory area, which memorize information depending on the difference of threshold voltages. The first nonvolatile memory area has the maximum variation width of a threshold voltage for memorizing information set larger than that of the second nonvolatile memory area. When the maximum variation width of the threshold voltage for memorizing information is larger, since stress to a memory cell owing to a rewrite operation of memory information becomes larger, it is inferior In a point of guaranteeing the number of times of rewrite operation; however, since a read current becomes larger, a read speed of memory information can be expedited.

  • Patent number: 7464210
    Abstract: This invention provides a data processing system capable of performing an interrupt exception handling routine as many times as the number of times of occurrence of a request event for the same interrupt exception handling routine if the request event occurs a plurality of times. A software interrupt counter or a hardware interrupt counter for retaining the number of times of occurrence of an interrupt request generation event counts up when a software processing which generates a software interrupt or a hardware event that generates a hardware interrupt occurs, and counts down when a CPU performs a processing for removing the interrupt request. If the value of the software interrupt counter and the value of the hardware interrupt counter are not zero, a software interrupt request signal and a hardware interrupt request signal to the CPU are asserted.

  • Publication number: 20080046697
    Abstract: The present invention prevents a data processor from undesirable operation stop due to an overflow of a plurality of register banks. A status register includes an overflow flag to indicate an overflow of the plurality of register banks. When an interrupt exception occurs in a state in which data has been saved to all banks of the register banks, and the accepted interrupt exception is permitted to use the register banks, a central processing unit saves data of a register set to a stack area and reflects an overflow state in the overflow flag. When the overflow flag indicates an overflow state, if data restoration from the register banks to the register set is directed, the central processing unit restores the data from the stack area to the register set.
