When talking about CPU specifications, in addition to clock speed and number of cores/threads, ' CPU cache memory ' is sometimes mentioned. Developer Gabriel G. Cunha explains what this CPU cache ...

Caches are increasingly common in DSPs, but many DSP programmers are unfamiliar with their operation. This article explains how caches work, using the two-level cache in TI's C64x as an example. It ...

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 ...

When shopping for a new CPU, you're likely to come across many different CPU specifications, such as cores, clock speed, TDP, ...

The year so far has been filled with news of Spectre and Meltdown. These exploits take advantage of features like speculative execution, and memory access timing. What they have in common is the fact ...

System-on-a-Chip (SoC) designers have a problem, a big problem in fact, Random Access Memory (RAM) is slow, too slow, it just can’t keep up. So they came up with a workaround and it is called cache ...

One of the greatest challenges facing the designers of many-core processors is resource contention. The chart below visually lays out the problem of resource contention, but for most of us the idea is ...

This paper presents the architecture of a high performance level 2 cache capable of use with a large class of embedded RISC cpu cores. The cache has a number of novel features including advanced ...

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 ...
