The dynamics of hybrid systems with mode dynamics of different dimensions is described. The first part explores structural properties of such multi-mode multidimensional (M3D) systems. The second part considers such models under sequential switching at random times. More specifically, the backward Kolmogorov equation is derived. This is applied to a causally restricted hybrid system containing a mode...
This paper presents the application of the parallel power processing strategy to the sequential switching shunt regulator for its use with high parasitic capacitance solar arrays. The main idea consists in dividing the complete solar array into two types of sections, low power sections and high power sections. The controller has been devised in such a way that always one low power section switches...
With technology scaling, vulnerability to soft errors in random logic is increasing. There is a need for on-line error detection and protection for logic gates even at sea level. The error checker is the key element for an on-line detection mechanism. We compare three different checkers for error detection from the point of view of area, power and false error detection rates. We find that the double...
The line (block) size of a cache memory is one of the parameters that most strongly affects cache performance. In this paper, we study the factors that relate to the selection of a cache line size. Our primary focus is on the cache miss ratio, but we also consider influences such as logic complexity, address tags, line crossers, I/O overruns, etc. The behavior of the cache miss ratio as a function...
