WebThe serial connection is also known as the daisy chaining method. Under this interrupt system environment, there is a hardware-priority-interrupt unit that functions as an overall manager performing the responsibility of: i. Accepting interrupt requests from many sources; ii. Determining which of the incoming requests has the highest priority; iii. WebIn daisy chaining method of interrupt handling, the devices are connected serially in such a manner that nearest device to the CPU has the highest priority, followed by the next device and so on.

"WebIt is a strict priority-based scheduling scheme in which a process runs until it is preempted or terminates. The term FIFO simply refers to the fact that, within a priority, processes run in first-come first-served order. We already saw the sched_setscheduler () function that allows a process to set a scheduling policy. " - Daisy chain priority interrupt

WebThis creates a priority chain where the modules on the left are a higher priority than modules on the right. Typical uses for a daisy chain are the Z80 mode 2 interrupt priority, IEI and IEO signals. This is specified as using pins 39 and 38. The second chain, using pins 43 and 42 can be used for a DMA priority chain.

WebThe trick is to use a one-of-7 priority encoding for interrupt vector number, eg. 0x00 highest priority then 0x02, 0x06, 0x0E, 0x1E, 0x3E, 0x7E, 0xFE lowest priority. Data bus would have pull ups - they can be gated by VECRQ described below, if you want to decrease general bus loading a bit. WebDaisy chaining is used for level sensitive interrupts, which act like a wired 'OR' gate. Any requesting device can take the interrupt line low, and keep it asserted low until it is serviced. Because more than one device can assert the shared interrupt line simultaneously, some method must be employed to ensure device priority.
