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 ...

System-on-chip (SoC) architects have a new memory technology, last level cache (LLC), to help overcome the design obstacles of bandwidth, latency and power consumption in megachips for advanced driver ...

Exponential increases in data and demand for improved performance to process that data has spawned a variety of new approaches to processor design and packaging, but it also is driving big changes on ...

What do you get when you cross a modern super-scalar out-of-order CPU core with more traditional microcontroller aspects such as no virtual memory, no memory cache, and no DDR or PCIe controllers? You ...

Check out our coverage of the 2023 Flash Memory Summit. This article is also part of the TechXchange: CXL for Memory and More. PCI Express (PCIe) is the de facto standard peripheral interface. Running ...

The number of options for choosing the best processor for embedded-system designs continues to increase. In addition to microprocessors, microcontrollers, and DSPs (digital-signal processors), several ...

Integrating processors, sensors, and data exchange functionality into everyday objects, the Internet of Things (IoT) pushes computing capabilities far beyond desktops and servers. On December 5, ...

The key issues that you need to address when designing high-speed multiprocessor (MP) systems include arbitration, bus bandwidth, and cache coherency. Arbitration ensures that only one master controls ...

AMD’s 7800X3D and 7950X3D hold the top spot in CPUs for gaming, not because they have the most cores or the highest clock speeds, but because they have the most cache. But what is CPU cache, anyway?
