WebA software interrupt occurs when an application program terminates or requests certain services from the OS. Usually, the processor requests a software interrupt when certain conditions are met by executing a special instruction. This instruction invokes the interrupt and functions like a subroutine call. WebAll software interrupts, as mentioned in the article, are technically synchronous, since they are initiated by the CPU itself - which is a synchronous circuit. Since no external devices share the same common clock as the CPU, all external interrupts can be said to be asynchronous.
