    摘要： A clipping processor capable of setting a clipping area, which has a shape not restricted to a rectangle and is defined in the processing of transferring data on a part of a clipping area in each raster by computing data defining the clipping area by two function generation circuits or by reading the data defining the clipping area from the clipping area memory, in which data defining a part of the clipping area in each raster is preliminarily stored, every time the raster is updated.

    摘要： A program translator has the following units:
    An option direction unit for directing a code generation unit to generate or not to generate an amendment instruction to compensate an overflow in an arithmetic operation.
    A code generation unit for generating an amendment instruction to compensate an overflow by discriminating the type of a data variable to be an operand for an arithmetic operation of a machine instruction when effective width of the data variable designated by an operand is smaller than the width of a register to store the data variable and when an overflow may be caused.

    摘要： The present invention discloses a program converting unit for generating a machine language instruction from a source program for a processor that manages an N-bit address while processing M-bit data, N being greater than M, and such a processor that runs the converted program. The program converting unit comprising: a parameter holding unit for holding a data width and a pointer width designated by a user, the data width representing the number of bits of data used in the source program while the pointer width representing the number of bits of an address; and a generating unit for generating an instruction to manage the data width when a variable operated by the instruction represents the data, and for generating an instruction to manage the pointer width when a variable operated by the instruction represents the address.
