The capabilities of seven dynamic buffer overflow detection tools (Chaperon, Valgrind, CCured, CRED, Insure++, ProPolice and TinyCC) are evaluated in this paper. These tools employ different approaches to runtime buffer overflow detection and range from commercial products to opensource gcc-enhancements. A comprehensive testsuite was developed consisting of specifically-designed test cases and ...

This paper describes the hardware F-Buffer implementation featured in the latest ATI graphics processors. We discuss the implementation choices made in each chip and the various implementation challenges faced like overflow handling. The F-Buffer was originally intended as a solution for multi-pass shading. We demonstrate this functionality, comparing it to traditional multi-pass rendering tech...

BACKGROUND Artificial boundaries on a map occur when the map extent does not cover the entire area of study; edges on the map do not exist on the ground. These artificial boundaries might bias the results of animal dispersal models by creating artificial barriers to movement for model organisms where there are no barriers for real organisms. Here, we characterize the effects of artificial bound...

This paper addresses the problem of calculating optimum buffer size for a dynamic voltage scaling processor. We determine the minimum required buffer size giving minimum energy solution for periodic (single, multiple) or aperiodic tasks. The calculations are based on information about data size (maximum, minimum), execution time (best case, worst case), and deadlines.
