摘要： A circuit for controlling the access to at least one area of a memory accessible by a program execution unit, including a first instruction address input; at least one second data address input, the addresses coming from the execution unit; at least one function of correlation of these addresses; and at least one output of a bit for validating the fulfilling of conditions set by the correlation function.

摘要： A method and a system of sharing of a clock by an electronic circuit between at least one first task clocked by at least one first counter and at least one second task clocked by a second counter, the two counters varying at the rate of said clock, the content of the first counter plus or minus an offset value being, on each execution of the second task, assigned to the second counter.

摘要： A method for authorizing an access to a table of address correspondence between a multitask CPU and at least one memory containing several programs, consisting of calculating, on each task change of the CPU, a signature of at least part of the program instruction lines, and checking the conformity of this signature with a signature recorded upon previous execution of the involved program.
