A method for executing a program includes: storing, in a table associated with each address of a specialized code of a parameterized function, a value of each of specialized parameters for generating the specialized code, and each time the address of a specialized code must be modified, deleted from, or added to the table, a microprocessor generates and records in a memory a search routine written in machine language of the microprocessor, this search routine containing, coded as constants, each address and each specialized parameter value stored in the table, such that the search routine does not include any reading operation of the value of a specialized parameter or of the address of a specialized code outside the continuous address range in which this search routine is recorded, and the microprocessor runs this recorded search routine directly.

Method for executing a computer program with a parameterised function

A method for executing a program including updating a value of a first counter each time a parameterized function is implemented with a first specific value of a parameter; checking whether the value of the first counter exceeds a first precalculated threshold, and in response, generating a specialized code for this function; and executing the preceding operations replacing the first specific value, the first counter, and the first precalculated threshold by a second specific value, a second counter and a second precalculated threshold, respectively; the first precalculated threshold being calculated on the basis of an execution outlay when the first specific value is used, the second precalculated threshold being calculated on the basis of an execution overlay when the second specific value is used.
