Direct Access to Working Memory Contents
Experimental Psychology, 2010In two experiments participants held in working memory (WM) three digits in three different colors, and updated individual digits with the results of arithmetic equations presented in one of the colors. In the memory-access condition, a digit from WM had to be used as the first number in the equation; in the no-access condition, complete equations ...

Automatic Loop Tiling for Direct Memory Access
2011 IEEE International Parallel & Distributed Processing Symposium, 2011In heterogeneous multi-core systems, such as the Cell BE processor, each accelerator core has its own fast local memory without hardware supported coherence and the software is responsible to dynamically transfer data between the fast local and slow global memory. The data can be transferred through either a software controlled cache or a direct buffer.

In this chapter we discuss the Direct Memory Access (DMA) functionality of the Cell architecture. Sender and receiver initiated DMA plays a significant role in program optimization. We present the DMA engine, fence and barrier concept for ordering data transfers. The DMA engine can be used as an additional data movement processor using dma-list. Double-

Optimizing Overlapped Memory Accesses in User-directed Vectorization
Proceedings of the 29th ACM on International Conference on Supercomputing, 2015Current processors incorporate wide and powerful vector units whose optimal exploitation is crucial to reach peak performance. However, present autovectorizing compilers fall short of that goal. Exploiting some vector instructions requires aggressive approaches that are not affordable in production compilers.
