Abstract:
PROBLEM TO BE SOLVED: To test the robustness of a component to frequency dispersion and fluctuation by transmitting clock signals having different frequencies to a transmitter for a binary signal to be multiplexed and a transmitter for a multiplexed binary signal. SOLUTION: A clock generator 9 transmits clock signals CLK2, CLK3 to a transmitter 2 and a transmitter 3, respectively, and the output of the transmitter 2 is inputted to a circuit 4 of multiplexer, further inputted to a data processing circuit 7 and transmitted to a receiver 3 through a circuit 5 of reverse multiplexer. At this time, the clock generator 9, the transmitter and receivers 2, 3 and a link 6 constitute the circuits 4, 5, and the data processing circuit 7 constitutes a component to be tested or a circuit B. The receiver 3 compares the binary signal directly received from the transmitter 2 with the binary signal from the circuit 5. Namely, the influence of frequency dispersion and fluctuation on the component to be tested can be simulated by controlling the different clock signals CLK2, CLK3, and the function failure can be tested.

Abstract:
The invention relates to a method of configuring a memory space (MEM), comprising the following steps consisting in: reading a configuration datum (SZ3) in the memory space (MEM) and dividing at least part of the memory space into memory areas (Z1-Z4) as a function of the configuration datum read; and assigning each memory area with an access number (NBK) that is used to access a datum location in the memory area, together with a logical address of the location in the memory area. The invention is suitable for RFID chips.
Abstract:
The inventive method for monitoring a program execution by a processor (14) consists in collecting and transmitting monitoring data. Said monitoring data is serialised prior to the transmission thereof and, afterwards reconstituted in a program execution device. The same clock pulse unit (170) is used for serialising at least a part of monitoring data and for clocking another data serialisation which can relate to data produced by the program execution or to another part of monitoring data.
