The 4×4 VP8 and AVS-M fast forward transforms are developed by cost-sharing hardware for multi-standard video encoding applications. By matrix factorizations, our proposed 1D hardware-sharing transform architecture is realized by only shifters and adders. Compared with the directly combined fast algorithms without hardware-sharing functionality, our proposed architecture reduces the number of shifters and adders by 24.5% and 73.4%, respectively. Compared with existing multi-standard transform designs, our proposed architecture reveals larger normalized hardware efficiency. Our proposed hardware sharing based 1-D forward transform supports the Full HD (1920×1080@60Hz) specification with the 110.8MHz working frequency.","PeriodicalId":6495,"journal":{"name":"2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73908727","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}

Two identical RAs are concurrently used which are in turn corrected for absolute gain value. Although the main RA is disconnected from data path for calibration, however, is replaced by a corrected one and resolves discontinuous conversion in regular foreground methods. A digitally assisted interface, includes inc/dec ACC and DAC, is utilized to store the loop results, even if RA leaves the correction loop. Monte-Carlo analysis for 100 iterations at all corner conditions shows that the correction loop provides ideal gain of 4 with median value of 3.996 and standard deviation of 0.003, while threshold voltages and reference levels experience 25mVolts variations at 3σ in Gaussian distribution. Linearity, drops to 9-bit for 50mVolts peak-to-peak variations on residue.

In the proposed class-E rectifier, a harmonic component is added to the switching device of the basic class-E rectifier. Therefore, the proposed class-E rectifier possesses the strengths of both the class-E and -F rectifiers, enabling simple configuration, low peak switch voltage, and high efficiency. A design example is given along with the PSpice-simulation waveforms. The switch voltage and current waveforms from the PSpice simulation satisfy the zero-voltage and zero-current soft switching conditions, namely, the switch voltage and current reach zero in the turn off and on instants, respectively. Therefore, the proposed class-E rectifier can achieve high power-conversion efficiency at high frequencies. Additionally, the peak switch voltage is reduced significantly compared with the basic class-E rectifier but the circuit configuration is as simple as the basic class-E rectifier. It is seen from the PSpise-simulation results that the numerical calculations agreed with the simulated ones quantitatively, which validated the accuracy and effectiveness of the proposed rectifier.","PeriodicalId":6495,"journal":{"name":"2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73217914","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 NVFF adds four transistors and two complementary magnetic tunnel junctions (MTJs) over a standard volatile flip-flop with only 18% area overhead. The NVFF utilizes a low power/ fast switching MTJ that permits the elimination of the write circuitry existing in conventional STT-NVFFs. The proposed NVFF is at least 80% smaller area than conventional STT-NVFFs that uses write circuitry with, at least, the same energy efficiency. It achieves a low backup energy of 111 fJ and restore energy of 6.9 fJ within 3 ns and 0.16 ns respectively. Moreover, it realizes a 72% reduction in break-even point (BEP) and a 10% area reduction compared to an STT-NVFF employing the latch as a writer.","PeriodicalId":6495,"journal":{"name":"2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74325968","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}
