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 ...

Direct memory access (DMA) is a means of having a peripheral device control a processor’s memory bus directly. DMA permits the peripheral, such as a UART, to transfer data directly to or from memory ...

In the world of computers, the central processing unit (CPU) is–well–central. Your first computer course probably explained it like the brain of the computer. However, sometimes you can overload that ...

Memory management is a critical aspect of modern operating systems, ensuring efficient allocation and deallocation of system memory. Linux, as a robust and widely used operating system, employs ...

Last time, in Part 1, we introduced somebasics behind Direct Memory Access (DMA) -why it's needed, and how it's structured and controlled. This time,we'll focus on the classifications of DMA transfers ...

Xsystems has introduced TrueNAS 25.10 "Goldeye", which can be connected to super-fast storage systems with NVMe-oF. It also ...

TrueNAS 25.10 has two ways to use this tech. If you want broad compatibility and don’t want to mess with specialized hardware ...

The hyperscalers and cloud builders are not the only ones having fun with the CXL protocol and its ability to create tiered, disaggregated, and composable main memory for systems. HPC centers are ...

A team from the Computer Architecture and Memory Systems Laboratory (CAMEL) at KAIST presented a new compute express link (CXL) solution whose directly accessible, and high-performance memory ...

The manufacturers have issued BIOS updates to address the issues, but researchers warn DMA attacks are likely possible against a range of laptops and desktops. Vulnerabilities in Dell and HP laptops ...
