Small filter caches (L0 caches) can be used to obtain significantly reduced energy consumption for embedded systems, but this benefit comes at the cost of increased execution time due to frequent L0 cache misses. The Instruction Register File (IRF) is an architectural extension for providing improved access to frequently occurring instructions. An optimizing compiler can exploit an IRF by packi...

Given a sequence of n elements, the All Nearest Smaller Values (ANSV) problem is to nd, for each element in the sequence, the nearest element to the left (right) that is smaller, or to report that no such element exists. Time and work optimal algorithms for this problem are known on all the PRAM models 3], 5], but the running time of the best previous hypercube algorithm 6] is optimal only when...

BACKGROUND The RD(50) (exposure concentration producing a 50% respiratory rate decrease) test evaluates airborne chemicals for sensory irritation and has become an American Society for Testing and Materials (ASTM) standard method. Past studies reported good correlations (R(2)) between RD(50)s and the occupational exposure limits, particularly threshold limit values (TLVs). OBJECTIVE The main ...

Time and work optimal algorithms for this problem are known on all the PRAM models 4, 6], but the running time of the best previous hypercube algorithm 9] is optimal only when ...

The paper examined the value system in Philippine firms against the backdrop of Eastern-Western cultural dynamics in East Asia. The Asian milieu presents co-existence of cultural stasis and unease -balance and tension between Eastern values and Western ideas. Successful Asian countries demonstrated their ability to blend conflicting cultures and highlight certain values in order to promote nati...

Modern microprocessor designs implement register renaming using register alias tables (RATs), which maintain the mapping between architectural and physical registers. Because of the non–trivial power that is dissipated in a disproportionately small area, the power density in the RAT is significantly higher than in some other datapath components. In this paper, we propose mechanisms to reduce th...

Memory access operations constitute about 32.7% of all the operations executed in a typical Prolog program. Among these memory accesses, 75% are to the program control structures (environments and choice points). These memory accesses plus possible data cache misses greatly impair system performance, and the problem is even more severe in a VLIW, superscalar, or superpipelined Prolog system. Th...

To store secrets and sensitive data in secure ways is necessary in the modern life. Since most hardware technologies used to store sensitive data are expensive for a single user, it is very common to store this kind of data by the means of software or software implemented encryption procedures. If for example the secret to protect is the secret key in a Public Key Infrastructure environment it ...
