On methods for direct memory access without cycle stealing

Microprocessing and Microprogramming, 1986
Abstract In hard real-time environments, it is necessary to determine in advance the run-times of tasks and to guarantee very short reaction times. Hence, the degradation of the processor speed by peripheral devices directly accessing the system memory by stealing memory cycles becomes a problem.

Direct Memory Access Optimization in Wireless Terminals for Reduced Memory Latency and Energy Consumption

Lecture Notes in Computer Science, 2007
Today, wireless networks are becoming increasingly ubiquitous. Usually several complex multi-threaded applications are mapped on a single embedded system and all of them are triggered by a single wireless stream (which corresponds to the dynamic run-time behavior of the user).

Direct distributed memory access for CMPs

Journal of Parallel and Distributed Computing, 2014
On-chip distributed memory has emerged as a promising memory organization for future many-core systems, since it efficiently exploits memory level parallelism and can lighten off the load on each memory module by providing a comparable number of memory interfaces with on-chip cores.

Automatic Loop Tiling for Direct Memory Access

2011 IEEE International Parallel & Distributed Processing Symposium, 2011
In 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.

Fast and Consistent Remote Direct Access to Non-volatile Memory

50th International Conference on Parallel Processing, 2021
For performance benefits, recent trends of modern data centers tend to use NVM (Non-volatile Memory) as storage and utilize one-sided primitives of RDMA (Remote Direct Memory Access) to directly access NVM for I/O requests. However, one-sided RDMA doesn’t have durability semantics currently, and data may partially exist in the NVM when crashes happen ...

Optimizing Overlapped Memory Accesses in User-directed Vectorization

Proceedings of the 29th ACM on International Conference on Supercomputing, 2015
Current 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.

Direct memory access digital events analyzer

Review of Scientific Instruments, 1989
We present a random-point-process multifunction analyzer in which a long sequence of interpulse intervals are recorded in the RAM bank of a personal computer, through a suitably designed front end attached to a commercial DMA interface. Laser light scattered by ground-glass disks and by aqueous suspensions of polystyrene latex spheres has been used to ...

Programming direct memory access data acquisition

TrAC Trends in Analytical Chemistry, 1990
Abstract Direct memory access data acquisition is an efficient means of collecting data from analytical instrumentation. Its adoption and implementation by chemists has been limited previously by its perceived complexity. This article introduces readers to this useful technique, and provides some routines which can be modified to suit their own needs.

Forca: Fast and Atomic Remote Direct Access to Persistent Memory

2018 IEEE 36th International Conference on Computer Design (ICCD), 2018
For promising performance boost, recent trends of modern data centers tend to use Persistent Memory (PM) as storage and utilize the one-sided feature of Remote Direct Memory Access (RDMA) to directly access PM for I/O requests. However, accessing PM through one-sided RDMA faces two challenges: one-sided data races and remote data crash consistency ...
