One of the key challenges in chip multi-processing is to provide a programming model that manages cache coherency in a transparent and efficient way. A large number of applications designed for ...

The past decade or so has seen some really phenomenal capacity growth and similarly remarkable software technology in support of distributed-memory systems. When work can be spread out across a lot of ...

The Cache Coherent Interconnect for Accelerators standard, or CCIX (pronounced “see 6”), is built on PCI Express (PCIe) to provide a chip-to-chip interconnect for high-speed hardware accelerators. It ...

In the first part of this series on the proposed Cache Coherence Interconnect for Accelerators (CCIX) standard, we talked about the issues of cache coherence and the need to share memory across ...

In the world of regular computing, we are used to certain ways of architecting for memory access to meet latency, bandwidth and power goals. These have evolved over many years to give us the multiple ...

Cache coherency, a common technique for improving performance in chips, is becoming less useful as general-purpose processors are supplemented with, and sometimes supplanted by, highly specialized ...

While traditional single core systems employ a dedicated cache, theintroduction of multi-core platforms presents the opportunity toconsider the shared use of cache by multiple processors. Designs ...

Open Core Protocol (OCP) [1][2] is a common standard for Intellectual Property (IP)core interfaces. OCP facilitates IP core plug-and-play and simplifies reuse by decoupling the cores from the on-chip ...

Cache memory significantly reduces time and power consumption for memory access in systems-on-chip. Technologies like AMBA protocols facilitate cache coherence and efficient data management across CPU ...

A Cache-Only Memory Architecture design (COMA) may be a sort of Cache-Coherent Non-Uniform Memory Access (CC- NUMA) design. not like in a very typical CC-NUMA design, in a COMA, each shared-memory ...

In the eighties, computer processors became faster and faster, while memory access times stagnated and hindered additional performance increases. Something had to be done to speed up memory access and ...
