Probabilistic Timing Analysis (PTA) is a recent technique to compute the execution time of a program within a given confidence interval, but requires specially designed hardware with certain properties. This work addresses the implementation of a probabilistically analyzable L1 instruction and data cache for the Ion MIPS32 processor on FPGA. We developed a random placement and replacement policy that fulfills all the requirements for PTA. Our experiments show that the cache fulfills all the requirements for PTA, and program timing can be determined with arbitrary accuracy. In addition, random placement and replacement improve the observed worst case execution time (WCET) from 6% to 19% w.r.t. a Least Recently Used policy.","PeriodicalId":404655,"journal":{"name":"2015 IEEE 13th International New Circuits and Systems Conference (NEWCAS)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123891304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To minimize the degradation in power transfer efficiency, the proposed system dynamically adjusts the capacitance of MCRs as the distance between the transmitter (TX) and receiver (RX) coils changes. The control unit operates in a self-sufficient manner through rectifying a portion of the AC signal present on TX and RX coils. A proof-of-concept circuit operating at 13.56 MHz is designed in a 0.13 μm CMOS technology and simulation results confirm the validity of the proposed scheme.","PeriodicalId":404655,"journal":{"name":"2015 IEEE 13th International New Circuits and Systems Conference (NEWCAS)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121165380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An analysis of the effect of the repartition of the spectral resources on the signal to interference plus noise ratio of the signal exchanged in the radio frequency network on chip is described in the content of this paper, where the final purpose is the optimizing of the overall throughput.

The concept of the EI is different from build-in self test (BIST) and other kinds of monitors by the fact that embedded instruments can provide the user with rich and detailed information with respect to the performances of the target, not just a true/false indication. In this paper, two embedded instruments for analogue and mixed-signal IPs focusing on dependability applications are introduced. They are the EI for measuring MOS transistors' threshold voltage and the EI for testing OpAmps' gain and offset. Measurements as well as simulation results are provided to validate these EIs and show their efficiency in monitoring the ageing of analogue and mixed-signal IPs in their life time, and enable the path to enhance dependability.","PeriodicalId":404655,"journal":{"name":"2015 IEEE 13th International New Circuits and Systems Conference (NEWCAS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114082528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed load tracking-zero compensation circuit not only eliminates the need for a bulky external off-chip capacitor that is typically employed in conventional compensation techniques, but also consumes very low additional quiescent current of 7.5μA that makes this method highly suitable for integrated SoC power management applications. It is demonstrated that this compensation technique, designed for the LDO in 130-nm CMOS technology, improves the stability and enhances the load regulation of the low dropout regulator.","PeriodicalId":404655,"journal":{"name":"2015 IEEE 13th International New Circuits and Systems Conference (NEWCAS)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114813860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
