    摘要: There is provided a semiconductor circuit for arithmetic processing and an arithmetic processing method that can increase the rate of processing data and reduces the area of a circuit by suppressing wasteful processing. There is provided a computing unit for computing input data within a computation time unit and outputs a computation result representing a result obtained by the computation, and if a carry is generated in the computation a computation circuit (adders 1-3) for outputting carry data representing this carry, and delay means (memory 4) for delaying the computation result from the computation circuit by one computation time unit, are provided.

    摘要: The buffer control device of this invention includes: a pointer holding unit which holds a virtual pointer different from a read pointer and a write pointer; an access control unit that controls an access to a ring buffer; a judging unit that judges whether or not one of the read pointer and the write pointer has reached an address substantially identical to an address indicated by the virtual pointer; and disabling unit that disables a normal access using the one of the read pointer and the write pointer, when the judging unit judges that the one of the read pointer and the write pointer has reached the address substantially identical to the address indicated by the virtual pointer, the normal access being controlled by the access control unit, wherein the access control unit further controls a reaccess to the ring buffer.
