    Abstract: A digital signal processor is designed to execute variable-sized instructions that may include up to N elementary instruction codes. The processor comprises a memory program comprising I individually addressable, parallel-connected memory banks in which the codes of a program are recorded in an interlaced fashion, and a circuit for reading the program memory arranged to read a code in each of the I memory banks during a cycle for reading an instruction. A cycle for reading an instruction in the program memory includes reading a sequence of codes that includes the instruction code or codes to be read and can also include codes, belonging to a following instruction, that are filtered before the instruction is applied to execution units. The program memory of the digital signal processor does not include any no-operation type codes.

    Abstract: A filtering circuit includes circuits for delivering first and second ramp-shaped signals when a logic signal to be filtered changes values, and includes logic circuits each with a switching threshold, for receiving the ramp-shaped signals. A memory unit delivers an output signal having a first value when outputs of the logic circuits have a first pair of values, and delivers a second value when the outputs of the logic circuits have a second pair of values. The filtering circuit may be applied to the filtering of an external clock signal in serial type memory devices.

    Abstract: An amplifier includes an input stage with one or more input terminals for receiving a signal to be amplified, and an output terminal. An inverting gain stage includes an input terminal connected to the output terminal of the input stage, an output terminal for delivering an amplified signal, and a variable feedback resistor connected between the output terminal and input terminal thereof.

    Abstract: Processes are provided for fabricating a substrate having a silicon-on-insulator (SOI) or silicon-on-nothing (SON) architecture, which are applicable to the manufacture of semiconductor devices, especially transistors such as those of the MOS, CMOS, BICMOS, and HCMOS types. In the fabrication processes, a multilayer stack is grown on a substrate by non-selective full-wafer epitaxy. The multilayer stack includes a silicon layer on a Ge or SiGe layer. Active regions are defined and masked, and insulating pads are formed so as to be located around the perimeter of each of the active regions at predetermined intervals and placed against the sidewalls of the active regions. The insulating trenches are etched, and the SiGe or Ge layer is laterally etched so as to form an empty tunnel under the silicon layer. The trenches are filled with a dielectric. In the case of an SOI archiutecture, the tunnel is filled with a dielectric.

    Abstract: A method of determining the time for polishing the surface of an integrated circuit wafer on a polishing machine. A sample wafer is fabricated to include at least one high plateau and at least one low plateau joined by a sudden transition. At least one initial profile is topographically scanned, and the surface of the sample wafer is polished at a particular polishing pressure for a particular polishing time. The final profile of the polished layer is topographically scanned in the corresponding area, and the initial and final topographical scans of the sample wafer are converted into Fourier series. The surface of the wafer to be polished is topographically scanned, and the topographic scan of the wafer to be polished is converted into a Fourier series. The time for polishing the wafer to be polished is calculated from the Fourier series and the average thickness to be removed.
