DRAM row buffer conflicts can increase memory access latency significantly. This paper presents a new pageallocation-based optimization that works seamlessly together with some existing hardware and software optimizations to eliminate significantly more row buffer conflicts. Validation in simulation using a set of selected scientific and engineering benchmarks against a few representative memory controller optimizations shows that our method can reduce row buffer miss rates by up to 76% （with an average of 37.4%）. This reduction in row buffer miss rates will be translated into performance speedups by up to 15% （with an average of 5%）.

This paper presents an automated code generation and validation, verification approach to convert model based developments into IEC 61131-3 conform function blocks. IEC 61131-3 programming languages are supported by PLC manufacturers and software environment developers and provide the possibility that novel and intelligent algorithms can be directly operated on industrial accepted systems. Railway and transportation also receive drastic changes from purely hardware based systems to microcontroller + software driven systems. However, the conversion has to follow certain steps to ensure that the adaptation is done correctly and functionality is not alternated, added or deleted. Concepts suggested by different international standards such as the IEC 61508 can help to derive a tool chain to verify the generated code.

Boolean Differential Calculus (BDC) extends Boolean *** Boolean algebra is focused on values of logic functions,BDC allows the evaluation of changes of the function values. Such changes can be investigated between certain pairs of function values as well as regarding whole subspaces. Due to the same basic data structures, BDC can be applied to any task described by logic functions and equations together with the Boolean *** used is BDC in analysis, synthesis, and testing of digital circuits. In this chapter, we introduce basic definitions of BDC together with some typical applications.
Domain feature models concisely express commonality and variability among variants of a software product line. For supporting separation of concerns, e.g., due to legal restrictions, technical considerations and busin...

Source code generation is an essential part of wide range of applications, including transcompilers, parser generators and preprocessors. The common technology based on code templates is often cumbersome and error-prone. This paper introduces syngen1, an automatic tool, written in Scheme, designed to produce frameworks for building syntactically correct fragments of source code. Copyright 2012 ACM.
This paper focuses on the latest version of a tool developed within the department to guide developer through the various steps of requirements, test-procedures and documentations to finally download the derived algor...
