Publication number: 20140035644Abstract: Adaptive scaling digital techniques attempt to place the system close to the timing failure so as to maximize energy efficiency. Rapid recovery from potential failures is usually by slowing the system clock and/or providing razor solutions (instruction replay.) These techniques compromise the throughput. This application presents a technique to provide local in-situ fault resilience based on dynamic slack borrowing. This technique is non-intrusive (needs no architecture modification) and has minimal impact on throughput.Type: ApplicationFiled: October 3, 2013Publication date: February 6, 2014Applicants: STMicroelectronics SA, STMicroelectronics International N.V.Inventors: Chittoor PARTHASARATHY, Nitin CHAWLA, Kallol CHATTERJEE, Pascal URARD

Publication number: 20140032188Abstract: The electric behavior of a reverse-biased PN junction diode is modeled by measuring the value of voltage V present across the diode and the value of the corresponding current I running through this diode, the voltage V varying within a range of values including the value of diode breakdown voltage. A representation of a function ln ? ( I - I s ) according to voltage V is established from the measured values of current I and of voltage V, IS being the saturation current of the diode. A linear function representative of a substantially linear portion of the function, characterized by voltages V greater than breakdown voltage VBK in terms of absolute value, is determined. An avalanche multiplication factor MM is then calculated by MM = 1 + ? ( - slbv · V + bv bv ) , with parameter slbv equal to the ordinate at the origin of the linear function, and parameter slbv/bv equal to the slope of the linear function.Type: ApplicationFiled: July 24, 2013Publication date: January 30, 2014Applicant: STMicroelectronics SAInventor: Jean-Robert Manouvrier
