Massive computation power and storage capacity of cloud computing systems allow scientists to deploy computation and data intensive applications without infrastructure investment, where large application data sets can be stored in the cloud. Based on the pay-as-you-go model, storage strategies and benchmarking approaches have been developed for cost-effectively storing large volume of generated application...
The trend of increasing digital system performance by downscaling the device size poses daunting challenges in system design due to the increased power density, higher I/O count, interconnect bandwidth, and timing closure requirements. Silicon carrier with Through Silicon Vias (TSVs) or TSI technology is identified as a system and packaging level solution to overcome all those challenges. In this...
We propose FSK/ASK re-modulation WDM-PON with coherent receiver. Apparent BER improvement is obtained by utilizing FSK image rejection receiver, especially for long distance transmission. Parameters in image rejection receiver which affect the system performance are analyzed. Results show that the presented scheme is promising in super long reach access network.
One of the most challenging problems in post-silicon validation is to identify those errors that cause prohibitive extra delay on speed paths in the circuit under debug (CUD) and only expose themselves in a certain electrical environment. To address this problem, we propose a trace-based silicon debug solution, which provides real-time visibility to the speed paths in the CUD during normal operation...
When testing delay faults on critical paths, conventional structural test patterns may be applied in functionally-unreachable states, leading to over-testing or under-testing of the circuits. In this paper, we propose novel layout-aware pseudo-functional testing techniques to tackle the above problem. Firstly, by taking the circuit layout information into account, functional constraints related to...
We propose and experimentally demonstrate a simple all-optical scheme to generation ultrawideband pulse utilizing dark RZ pulse generation. The effect of some key parameters in UWB generation on signal quality is also investigated.
