1. Hiding and Reducing Memory Latency : Energy-Efficient Pipeline and Memory System Techniques
Sammanfattning : Memory accesses in modern processors are both far slower and vastly more energy-expensive than the actual computations. To improve performance, processors spend a significant amount of energy and resources trying to hide and reduce the memory latency. LÄS MER
2. Advances Towards Data-Race-Free Cache Coherence Through Data Classification
Sammanfattning : Providing a consistent view of the shared memory based on precise and well-defined semantics—memory consistency model—has been an enabling factor in the widespread acceptance and commercial success of shared-memory architectures. Moreover, cache coherence protocols have been employed by the hardware to remove from the programmers the burden of dealing with the memory inconsistency that emerges in the presence of the private caches. LÄS MER
3. Securing the Memory Hierarchy from Speculative Side-Channel Attack
Sammanfattning : Modern high-performance CPUs depend on speculative out-of-order execution in order to offer high performance while also remaining energy efficient. However, with the introduction of Meltdown and Spectre in the beginning of 2018, speculative execution has been under attack. LÄS MER
4. Reconfigurable-Hardware Accelerated Stream Aggregation
Sammanfattning : High throughput and low latency stream aggregation is essential for many applications that analyze massive volumes of data in real-time. Incoming data need to be stored in a single sliding-window before processing, in cases where incremental aggregations are wasteful or not possible at all. LÄS MER
5. Optimizing Performance in Highly Utilized Multicores with Intelligent Prefetching
Sammanfattning : Modern processors apply sophisticated techniques, such as deep cache hierarchies and hardware prefetching, to increase performance. Such complex hardware structures have helped improve performance in general, however, their full potential is not realized as software often utilizes the memory hierarchy inefficiently. LÄS MER
