Radiation Hardened NULL Convention Logic Asynchronous Circuit Design
This paper proposes a radiation hardened NULL Convention Logic (NCL) architecture that can recover from a single event latchup (SEL) or single event upset (SEU) fault without deadlock or any data loss. The proposed architecture is analytically proved to be SEL resistant, and by extension, proved to be SEU resistant. The SEL/SEU resistant version of a 3-stage full-word pipelined NCL 4 × 4 unsign...
متن کاملAccurate Throughput Derivation of Pipelined NULL Convention Logic Asynchronous Circuits
A throughput estimation formula for optimally pipelining NULL Convention Logic (NCL) asynchronous circuits was presented in the literature. However, it ignores register delays. This paper presents a precise throughput derivation formula for pipelined NCL circuits. The formula was verified by Spice simulation and can be used for static timing analysis.
متن کاملDesign and Characterization of NULL Convention Arithmetic Logic Units
In this paper a number of 4-bit, 8-operation arithmetic logic units (ALUs) are designed using the delayinsensitive NULL Convention Logic (NCL) paradigm, and are characterized in terms of speed and area. Both dualrail and quad-rail, pipelined and non-pipelined versions are developed, and the tradeoffs and design considerations for each are discussed. Comparing the various architectures shows tha...
متن کاملAsynchronous circuit design
Specification for circuit usually trys to accomplish certain goals. Examples: Protocol never deadlocks. Whenever there is a request, it is followed by an acknowledgement possibly in a bounded amount of time. Can check by simulating a number of important cases. Simulation does not guarantee correctness of the design. Big problem in asynchronous design where a problem only manifests under a very ...
متن کاملA novel radiation hardened by design latch ∗
Due to aggressive technology scaling, radiation-induced soft errors have become a serious reliability concern in VLSI chip design. This paper presents a novel radiation hardened by design latch with high single-eventupset (SEU) immunity. The proposed latch can effectively mitigate SEU by internal dual interlocked scheme. The propagation delay, power dissipation and power delay product of the pr...
