Arithmetic Logic Unit (ALU): Performs arithmetic and logical operations. Register Files: Manages registers for data storage and manipulation. Control Unit: Directs the operation of the CPU by ...

Abstract: An interrupt controller is required in current pro-cessors to manage multiple asynchronous events while ensuring timely CPU response. In complicated embedded systems, the controller must ...

Abstract: The emergence of an open-source instruction set architecture (ISA) widely known as RISC-V has opened a new era of innovation within the realm of embedded systems. Interrupt handling is a ...

This project implements a virtual CPU in Python to simulate the basic operations and components of a computer's central processing unit. The goal was to understand how CPUs work at a fundamental level ...

Normal execution of a given software application is contained within the bounds of one program, or instruction stream. Such execution is provable, as well as traceable. However, system designers and ...

As a fully preemptive kernel, SST must ensure that at all times the CPU executes the highest-priority task that's ready to run. Fortunately, only two scenarios can lead to readying a higher-priority ...

Interrupts are a major feature of most embedded microcontrollers and effective real time response to interrupts is vital in low power systems that often rely on a ‘run fast then stop’ approach to ...
