The implementation of complex functionality in low-power nano-CMOS technologies leads to enhance susceptibility to parametric disturbances (environmental, and operation-dependent). The purpose of this paper is to present recent improvements on a methodology to exploit power-supply voltage and temperature variations in order to produce fault-tolerant structural solutions. First, the proposed methodology...
The purpose of TAFT fault tolerance studies conducted at CNES is to prepare the space community for the significant evolution linked to the usage of COTS components for developing spacecraft supercomputers. CNES has patented the DMT and DT2 fault-tolerant architectures with 'light' features. The development of a DMT/DT2 testbench based on a PowerPC7448 microprocessor from e2v is presented in this...
Polymorphic gates can be considered as a new reconfigurable technology capable of integrating logic functions with sensing in a single compact structure. Polymorphic gates whose logic function can be controlled by the level of the power supply voltage (Vdd) represent a special class of polymorphic gates. A new polymorphic NAND/NOR gate controlled by Vdd is presented. This gate was fabricated and utilized...
The design of a full integrated electronics readout for the next ILC ECAL presents many challenges. Low power dissipation is required, and it will be necessary to integrate together the very front-end stages with an analog to digital converter. We present here a 12 bit 30 MHz analog to digital converter using a pipelined architecture. It is composed by ten 1.5 bit sub-ADC with a final 2 bit flash...
In deep submicron era, to prevent larger amount of SRAM from more frequently encountered overheating problems and react accordingly for each possible hotspots, multiple ideal run-time temperature sensors must be closely located and response rapidly to secure system reliability while maintaining core frequency. This paper presented a method to extract run-time temperature information from multiple...
