CPU Power Management: CPUIDLE

Linux Kernel cpuidle subsystem architecture

CNXSoft: This is a guest post by Daniel Thompson, Principal Software Engineer at RISCtar Solutions, about Linux CPU power management for embedded systems, specifically covering cpuidle in depth. Twenty years ago, it was easy for an operating system kernel to go idle: when there were no tasks to run, “the idle loop” would be scheduled. Early idle loops were basically empty infinite loops that did nothing while waiting for the next interrupt to happen. This saved power simply by avoiding running instructions that needed power-hungry components such as the cache or FPU! Over time, changing technology has allowed multiple additional hardware mechanisms to reduce power to be introduced. With these new options available today, the idle loop is responsible for choosing and deploying the “best” way to go idle. As a brief reminder, entering and returning from an idle state has a cost, and that cost can be measured both […]

Revolut’s IPO is two years away, and it’ll be in the US

The CEO of Europe’s most valuable startup gave his clearest IPO timeline yet in a Bloomberg interview, narrowing his December ‘two to three years’ estimate to ‘two years.’ It came as Revolut marked the biggest regulatory milestone in its history and filed for a US bank charter, both developments that make an eventual listing meaningfully […]

AI Security Camera with IP67 Rating Featuring Rockchip RV1126B or RK3576/J/M SoC for Commercial, Industrial, and Automotive Use – CNX Software

Firefly CQ38W 1126B and CQ38W 3576 AI smart security cameras

Back in January 2024, Firefly released the CT36L AI smart security cameras, built around the Rockchip RV1106G2 SoC with a 0.5 TOPS NPU and Power over Ethernet (PoE) support. Now, Firefly has introduced two new AI cameras, the CQ38W-1126B and CQ38W-3576, which use a similar IP67-rated enclosure but come with much more powerful processors. Both new models no longer support PoE and instead use a 12V DC input, and they also add an RS485 interface. In terms of performance, the CQ38W-1126B is built around the Rockchip RV1126B with a 3 TOPS NPU and can run small multimodal AI models. The higher-end CQ38W-3576 features an octa-core Rockchip RK3576 with a 6 TOPS NPU, making it suitable for more demanding AI workloads, including YOLO and large language models. Both cameras are available with 3MP or 5MP sensors and come in Commercial or Industrial (J-suffix) variants. The 3576 series also adds an Automotive-grade […]
