WebJul 10, 2024 · Scatter/gather is used to do DMA data transfers of data that is written to noncontiguous areas of memory. A scatter/gather list is a list of vectors, each of which gives the location and length of one segment in the overall read or write request. ... The blue “sub-banks” are filled from DRAM via DMA. So, in fact, there will be two such SRAM ... WebAXI Multi-Channel DMA (with Scatter-Gather data transfer) and using it under Linux.

WebOct 14, 2024 · To overcome this bottleneck, we propose Ambit, an Accelerator-in-Memory for bulk bitwise operations. Unlike prior works, Ambit exploits the analog operation of DRAM technology to perform bitwise operations completely inside DRAM, thereby exploiting the full internal DRAM bandwidth. Ambit consists of two components. WebSep 28, 2015 · Lee+, “Decoupled Direct Memory Access: Isolating CPU and IO Traffic by Leveraging a Dual-Data-Port DRAM,” PACT 2015.

WebGather-Scatter DRAM. Cacheline-ID-based data shuffling (shuffle data of each cache line differently) Pattern ID – In-DRAM address . t. ranslation (locally compute column address at each chip) Challenge 1: Minimizing chip conflicts. Challenge 2: Shared address bus. Add “solution to challenge 1” etc. In existing systems, which are optimized to store and access cache lines, non-unit strided accesses exhibit low spatial locality. Therefore, they incur high latency, and waste memory bandwidth and cache space. We propose the Gather-Scatter DRAM (GS-DRAM) to address this problem.
