Network-on-chip based many-core processors break the limitations faced with single-core processors, and can bring high performance, improved yield, and high reliability. They are widely considered as the most promising platform. One of the most important questions is: what kind of granularity of cores (in other words, the number of cores and the area of each core under specific area constraint of...
Focusing on resolving the defects of control engineering compiler, such as monolingual support, or the high redundance and large amounts of multi-language support compiler, the paper proposed an approach to compile 5 standard languages of IEC61131-3, which reduced the complexity of the compiler and increased the reuse of codes. By means of analyzing the IEC61131-3, the standard language model was...
In a high-end database system, the execution concurrency level rises continuously in a multiprocessor environment due to the increase in number of concurrent transactions and the introduction of multi-core processors. A new challenge for buffer management to address is to retain its scalability in responding to the highly concurrent data processing demands and environment. The page replacement algorithm,...
Compared with rapid technology advancements in multicore processors and rapid changes from computing-intensive to highly data-intensive applications, operating systems have been evolved very slowly for several decades. Application users are facing to two major challenges in today's computing environment. On the top level of the system hierarchy, private and shared caches are equipped for many cores...
Cache partitioning and sharing is critical to the effective utilization of multicore processors. However, almost all existing studies have been evaluated by simulation that often has several limitations, such as excessive simulation time, absence of OS activities and proneness to simulation inaccuracy. To address these issues, we have taken an efficient software approach to supporting both static...
