  • Unroll of instructions in a micro-controller
    Patent number: 5828875
    Abstract: Loops in program code are avoided by generating instructions for controlling a processor. A first template instruction is stored, and a predetermined number of instructions may be generated, wherein each generated instruction is based on the first template instruction. The processor may be alternatively supplied with the generated instructions or with instructions received from an alternative instruction source. A substitute address field may be stored, and the step of generating each instruction may include substituting the substitute address field in place of an address field in the first template instruction. The stored substitute address field may be adjusted after generating each instruction. The step substituting the substitute address field in place of an address field in the first template instruction may be performed only if a substitution control signal is asserted.
