The DHRY program performs the dhrystone benchmarks on the 8051. Dhrystone is a general-performance benchmark test originally developed by Reinhold Weicker in 1984. This benchmark is used to measure and compare the performance of different computers or, in this case, the efficiency of the code generated for the same computer by different compilers. The test reports general performance in dhrystones per second. Like most benchmark programs, dhrystone consists of standard code and concentrates on string handling. It uses no floating-point operations. It is heavily influenced by hardware and software design, compiler and linker options, code optimizing, cache memory, wait states, and integer data types. The DHRY program is available in different Targets: Simulator: Large Model: DHRY example in LARGE model for Simulation Philips 80C51MX: DHRY example in LARGE model for the Philips 80C51MC

Introduction ? ? The ARM Cortex -A8 microprocessor is the first applications microprocessor in ARM!ˉs new Cortex family. With high performance and power efficiency, it Targets a wide variety of mobile and consumer applications including mobile phones, set-top boxes, gaming consoles and automotive navigation/entertainment systems. The Cortex-A8 processor spans a range of performance points depending on the implementation, delivering over to 2000 Dhrystone MIPS (DMIPS) of performance for demanding consumer applications and consuming less than 300mW for low-power mobile devices. This translates into a large increase in processing capability while staying with the power levels of previous generations of mobile devices. Consumer applications will benefit from the reduced heat dissipation and resulting lower packaging and integration costs.

DDSCAT 7.3 is a freely available open-source Fortran-90 software package applying the “discrete dipole approximation” (DDA) to calculate scattering and absorption of electromagnetic waves by Targets with arbitrary geometries and complex refractive index. The Targets may be isolated entities (e.g., dust particles), but may also be 1-d or 2-d periodic arrays of “target unit cells”, which can be used to study absorption, scattering, and electric fields around arrays of nanostructures.

Since the 1990s the EU has been pursuing climate change mitigation Targets. Following the international commitment to the legally binding greenhouse gas reduction under the Kyoto Protocol, the 2020 policy package consists of a set of binding legislation to ensure that the EU meets its climate and energy Targets for the year 2020. The package sets three key Targets: 20% reduction in greenhouse gas emissions (from 1990 levels), 20% of EU energy from renewables (as well as a 10% target for renewable fuels) and 20% improvement in energy efficiency. The Targets were set by EU leaders in 2007 and enacted in legislation in 2009 3 . They are also headline Targets of the Europe 2020 strategy for smart, sustainable and inclusive growth.
