Writing good, performant code depends strongly on an understanding of the underlying hardware. This is especially the case in ...

The CPU’s cache reduces memory latency when data is accessed from the main system memory. Developers can and should take advantage of CPU cache to improve application performance. Modern CPUs ...

Part 2 looks at the tradeoffs between program and data cache optimizations, and shows how to choose the best compromise. It will be published Monday, November 5. For more on this topic see Optimizing ...

The development of caches and caching is one of the most significant events in the history of computing. Virtually every modern CPU core from ultra-low power chips like the ARM Cortex-A5 to the ...

Now that there are embedded media processors available that can handle both MCU and DSP tasks, C programmers who are very familiar with the MCU model of application development are transitioning into ...
