The success of a software project is strongly related with architectural design. However, designing the right Software Architecture is a very subjective task and takes a long time, being much influenced by architect’s experience and the quality of requirements engineering. A big problem emerges when the trade-off among quality requirements is not properly solved during requirements engineering....

-It is demonstrated that usual time-memory trade-offs offer no asymptotic advantage over exhaustive search. Instead, trade-offs between time, memory, and parallel processing are proposed. Using this approach it is shown that most searching problems allow a trade-off between C,, the cost per solution, and C,,,, the cost of the machine: doubling C,,, increases the solution rate by a factor of fou...

Design of a successful product requires evaluating many design alternatives in a limited design cycle time. This can be achieved through leveraging design space exploration tools and available computing resources on the network. This paper presents a parallel trade study architecture to integrate trade study clients and computing resources on a network using Web services. The parallel trade stu...

A hardware/software trade-off is the establishment of the division of responsibility for performing system functions between the software, firmware and hardware. This is part and parcel of the fundamental process of defining computer architecture. It begins the day a computer is conceived and may be carried on by an ever widening group of individuals until the last computer of a given model is ...

1. Goal: high resolution and large bandwidth ADCs. 2. ADCs: oversampling, noise shaping, (one-bit quantizer); trade speed for resolution; trade analog-circuit accuracy for digital-circuit complexity. 3. Architecture: cascaded 2-0 delta-sigma (2-0 MASH) ADC; p robust stability and speed; high sensitivity to analog-circuit imperfections. 4. Issues of the MASH ADCs: designing the structure; handli...

This paper presents an attempt at an early investigation or exploration of the trade-off between MIPS cost and memory cost. The cost model is an approximation based on knowledge of the application behavior and algorithm inner loop costs for the hardware architecture, which consists of a control processor and a SIMD processor. The application is an H.264 video decoder. Various memory configurati...

The fishing industry not only acts as foreign exchange earner but also plays an important role in China’s economy. But with the development of technology and liberalization of international trade, the foreign countries adopted in succession trade barriers to limit China’s fishery product export, which had make China’s fishery product export disproportionated with fishery products production. By...

The ubiquitous trade-off between survival and costly reproduction is one of the most fundamental constraints governing life-history evolution. In numerous animals, gonadotropic hormones antagonistically suppressing immunocompetence cause this trade-off. The queens of many social insects defy the reproduction-survival trade-off, achieving both an extraordinarily long life and high reproductive o...
