This paper presents several low-latency mixed-timing
FIFO (first-in–first-out) interfaces designs that interface systems
on a chip working at different speeds. The connected systems
can be either synchronous or asynchronous. The designs are then
adapted to work between systems with very long interconnect
delays, by migrating a single-clock solution by Carloni et al.
(1999, 2000, and 2001) (for “latency-insensitive” protocols) to
mixed-timing domains. The new designs can be made arbitrarily
robust with regard to metastability and interface operating speeds.
Initial simulations for both latency and throughput are promising.
By building a nonlinear function relationship between an d the error signal，this paper presents a no—
vel variable step size LMS(Least Mean Square)adaptive filtering algorithm．
wavelets are used extensively in signal and image processing,Medicine, Finance, Radar, Sonar, Geology
and many other varied fields. They are usually presented in mathematical formulae, but can actually be
understood in terms of simple comparisons with your data.
