Exceptions in MIPS

1996, Virgil BistriceanuExceptions in MIPSO bjectivesAfter completing this lab you will: know the exception mechanism in MIPS be able to write a simple exception handler for a MIPS machineIntroductionBranches and jumps provide ways to change the control flow in a can also change thecontrol flow in a MIPS convention calls anexception any unexpected change in control flow regardless of its source ( distinguishing between a within the processor source and an external source).An exception is said to be synchronous if it occurs at the same place every time a program is executed withthe same data and the same memory allocation.

An interrupt is an asynchronous exception. Synchronous exceptions, resulting directly from the execution of the program, are called traps. When an exception happens, the control is transferred to a different program named exception handler , writ-ten explicitly for the purpose of …

Software Testing Strategies Chapter 18

www.cs.iit.edu

Software Testing Strategies • Characteristics of testing strategies: – Testing begins at the component level, for OO at the class or object level, and works outward toward the integration of the entire system. – Different testing techniques, such as white-box and black-box, are appropriate at different times in the testing process.

1.3 What Drives the Work of a Computer Designer Designing a computer is a challenging task. It involves software (at least at the level of designing the instruction set), and hardware as well at all levels: functional organization, logic design, implementation. Implementation itself deals with designing/specifying ICs, packaging,

Exception and Interrupt Handling in ARM

ic.unicamp.br

Interrupt handling schemes Prioritized simple interrupt handling • associate a priority level with a particular interrupt source. • Handling prioritization can be done by means of software or hardware. • When an interrupt signal is raised, a fixed amount of comparisons is done. • So the interrupt latency is deterministic.

Using Cortex-M3/M4/M7 Fault Exceptions

www.keil.com

The HardFault exception is always enabled and has a fixed priority (higher than other interrupts and exceptions, but lower than Non-Maskable Interrupt NMI). The HardFault exception is therefore executed in cases where a fault exception is disabled or when a fault occurs during the execution of a fault exception handler.

Exception and interrupt handling is a critical issue since it affect directly the speed of the system and how fast does the system respond to external events and how does it deal with more than one external event at the same time by assigning priorities to these events.
