A microprocessor is arranged to process instructions at least some of which contain at least one immediate value which forms an operand of the function, wherein said immediate value is represented in a format which achieves a greater power efficiency than two’s complement when said instructions are processed. The method and the apparatus use an image dataset in which a calibration object is captured by a camera. 0\u2003\u2003are satisfied at the same time, and the radial tire for a heavy load which is improved in a low fuel consumption and in which a tire durability is consistent with a reduction in a weigh can be provided. A controlled gene delivery system based on these polyphosphoesters is prepared by complex coacervation of nucleic acid with polymers.
