This paper proposes dynamic ramp control in current-mode adaptive on-time control for Buck converter on chip. It improves system stability and reduces output voltage at the load release. The concept of dynamic ramp control uses sample and hold circuit, comparator, and ramp valley control circuit adjusted according to the varied ramp signal to avoid the generation of an error pulse signal to regulate...
The reasoning error of existing high dimensional cloud model is large when some domains are correlated, and a correction high dimensional cloud model is proposed based on cloud model and multivariate normal distribution theory. The entropy and hyper entropy were replaced by covariance entropy and covariance hyper-entropy in the correction cloud model, which were used to describe the correlation of...
This paper proposes a new hardware accelerator to speed up the performance of vector graphics applications on complex embedded systems. The resulting hardware accelerator is synthesized on a field-programmable gate array (FPGA) and integrated with software components. The paper also introduces a hardware/software co-verification environment which provides in-system at-speed functional verification...
A nonlinear, Digitalized Modified-Logistic Map based Pseudo Random Number Generator (DMLM-PRNG) is proposed for randomness enhancement. We use parameter selection to reduce computation cost and output sequence scrambling to improve the quality or randomness. Statistical test results show that DMLM-PRNG passes all cases in SP800-22, and most of cases in Crush, one of the test suite of TesuU01. When...
