A structured top-down approach to the design of programs which use the traditional interrupt hardware is urged. The OCCAM language has been chosen for program notation because OCCAM was designed for the representation of parallel program activity, and interrupts inherently imply some sort of parallelism.doi:10.1016/0141-9331(85)90415-6Don F...
representation of memory and CPU utilization from the perspective of only the Cisco IOS process; they do not include information for resources on the entire platform. When theshow memorycommand is used in a system with 4 GB RAM running a single Cisco IOS process, the following memory usage...
Embedded software engineer interview questions will be devised to discover your expertise in one or more key skills. Interviewers will also look for knowledge of both hardware and software design and embedded systems. You can take an in-depth look into the skills required to become an Embedded sy...
Chapter: Environmental Monitoring and PoE Management Chapter Contents The Cisco Catalyst 8300 Series Edge Platform have hardware and software features that periodically monitor the router's environment. This chapter provides information on the environmental monitoring feat...
In the Internal interrupt mode the interrupts are not cleared automatically. It is the user’s responsibility to do this. The External interrupt mode is preferred in this case." It is only if hardware FIFO is used that external interrupts are available and preferred. If software FIFO is ...
embedded devices operate in total isolation and are not accessible to an operator. Manually resetting a device in this scenario when its software “hangs” is not possible. In extreme cases, this can result in damaged hardware or loss of life and incur significant cost impact. Watchdog Timers7...
control means, under control of control software, for reading and writing to said interrupt register for storing and deleting, under software control, said hardware interrupt request in said interrupt register; and selection means for selecting and transmitting one of said store interrupts in said int...

System and method for integrating software schedulers and hardware interrupts for a deterministic systemThe problem which is being addressed by this invention is the lack of determinism in mass market operating systems. This invention provides a mechanism for mass market operating systems running on ...
A method for managing interrupts in a microprocessor includes interrupts having a two-fold order of priority, i.e., a software priority and a hardware priority, wherein the microprocessor operates in two modes. During a first mode, the execution of an interrupt routine cannot be interrupted by...
