Basics of Raspberry Pi

RASPBERRY-PI

ARM11 FEATURES

The ARM1176™ applications processors deployed broadly in devices ranging from smart phones to digital TV's to eReaders, delivering media and browser performance, a secure computing environment, and performance up to 1GHz in low cost designs.

The ARM1176JZ-S processor features ARM TrustZone technology for secure applications and ARM jazelle  technology for efficient embedded Java execution.

Optional tightly coupled memories simplify ARM9processor migration and real-time design, while AMBA 3 AXI interfaces improve memory bus performance.

DVFS support enables power optimization below the best-in-class nominal static and dynamic power of the ARM11 processor architecture.

KERNEL LAYER

In computing the kernel is a computer program that manages input/output requests from software and translates them into data processing instructions for the central processing unit and other electronic components of a computer.

The kernel is a heart of a computer's operating system.
