An algorithm is presented for finding a root of a real function. The algorithm combines bisection with second and third order methods using derivatives estimated from objective function values. Globaql convergence is ensured and the number of function evaluations is bounded by four times the number needed by bisection. Numerical comparisons with existing(More)
Gamma was originally proposed in 1986 as a formalism for the deenition of programs without artiicial sequentiality. The basic idea underlying the formalism is to describe computation as a form of chemical reaction on a collection of individual pieces of data. Due to the very minimal nature of the language, and its absence of sequential bias, it has been(More)
An electrical and physical design power optimization methodology and design techniques developed to create an ARM 1136SF-S microprocessor in 9Onm standard CMOS are presented. A 40% reduction in power dissipation has been achieved while maintaining a 355 MHz operating clock rate under typical conditions. Functional and electrical design requirements were(More)
Overview The result of this thesis is the automatic version control system integrated into Eiffel Studio. This automatic version control system uses SVN to commit and update files. Version control systems allow people to go back to previous revisions of individual files, and to compare any two revisions to view the changes between them. More importantly,(More)

The study of software architectures has grown as an autonomous discipline recently. A widely accepted, and very general, characterisation of software architectures can be sketched as follows Shaw and Garlan, 19955: Software architecture is the level of software design that addresses the overall structure and properties of software systems". The success of(More)
A system-centric, fully-hierarchical design methodology and design techniques developed to create four ICs, which provide the core functionality of a multi-Gigabit switching network system, are presented. The system is capable of switching more than 500 million packets per second. Electrical and physical design methods for one IC are described. /spl sim/76(More)
