Write-through: all cache memory writes are written to main memory, even if the data is retained in the cache, such as in the example in Figure 4.11. A cache line can be in two states – valid or ...

Researchers at MIT’s Computer Science and Artificial Intelligence Lab have designed a system where programs can have access to ad hoc optimally allocated cache memory. In a simulation test system with ...

Multiple PC OEMs are selling laptops outfitted with Intel Optane cache drives -- but they're improperly combining that information in ways that makes it seem as if the Optane cache drive represents ...

For the past two decades, distributed caches, also known as in-memory data grids, have been used to address such challenges. By keeping fast-changing data in memory and distributing it in a cluster of ...

The i7 supports the x86-64 instruction set architecture, a 64-bit extension of the 80×86 architecture. The i7 is an out-of-order execution processor that includes four cores. In this chapter, we focus ...

How lossless data compression can reduce memory and power requirements. How ZeroPoint’s compression technology differs from the competition. One can never have enough memory, and one way to get more ...

In the most simple computer system architecture, all control lies with the CPU (Central Processing Unit). This means not only the execution of commands that affect the CPU’s internal register or cache ...

IBM Research has been working on new non-volatile magnetic memory for over two decades. Non-volatile memory is wonderful for retaining data without power, but it is extremely slow, and does not last ...

Memory is one of a very few elite electronic components essential to any electronic system. Modern electronics perform extraordinarily complex duties that would be impossible without memory. Your ...
