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 ...

Using different processors in a system makes sense for power and performance, but it’s making cache coherency much more difficult. Cache coherency is becoming more pervasive—and more problematic—as ...

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 ...

Cache, in its crude definition, is a faster memory which stores copies of data from frequently used main memory locations. Nowadays, multiprocessor systems are supporting shared memories in hardware, ...

The adoption of Linux is accelerating, as it is becoming the operating system of choice for a variety of embedded applications. However, designers of these performance-intensive, embedded SoCs running ...

With silicon clock scaling largely dead thanks to the laws of physics, computer scientists and chip designers have had to search for performance improvements in other areas -- typically by improving ...

Scaling processing performance beyond the frequency and power envelope of single core systems has led to the emergence of multi-core clusters. Data access management within such processing systems ...

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 ...

The speed race is over. Faced with the growing energy consumption andexcessive operating temperatures caused by high CPU clock speeds,microprocessor vendors have adopted a new approach to boosting ...
