HISR: High Level ISR (Interrupt Service Routine) LISR: Low Level ISR

embedded systems is good....but doing embedded systems is not easy..u should have good programming skills and good background in electronics....u should also have passion to do embedded systems.....
I believe a nested interrupt, is where an interrupt is allowed to occur (and thus is handled) during an already occurring Interupt service ruotine. I.E. First interrupt occurs ISR1 begins second Interrupt occurs ISR2 begins ISR2 Finishes ISR1 continues from where left off ISR1 finishes
Why embedded Systems demand have increased Today ? http://corvalent.com/02c_embedded_system...
Embedded systems are made only in C as it provides efficient memory management independence
In the 8085 microprocessor, a hardware interrupt is a signal from an external device that temporarily halts the CPU's current operations to allow the device to communicate with the processor. A vector interrupt specifically refers to an interrupt that has a predefined memory address (vector) associated with it, which the processor jumps to when servicing the interrupt. For instance, the 8085 has several hardware interrupts, such as INTR, RST 7.5, RST 6.5, and RST 5.5, each with its own unique vector address, allowing for efficient and organized handling of multiple interrupt sources. This mechanism enables real-time processing and responsiveness to external events in embedded systems.
An embedded operating system is an operating system for embedded computer systems. These operating systems are designed to be compact, efficient, and reliable, forsaking many functions that non-embedded computer operating systems provide, and which may not be used by the specialized applications they run.

Embedded systems can be run on very limited hardware and do not require a lot of extra "stuff" around. This also makes them excellent candidates as mobile systems.
Embedded systems are used to manage a certain operation inside of a device. Embedded systems are often merely made to carry out this task repeatedly, but more advanced ones can take control of whole operating systems.
Three common examples of an embedded systems include video game consoles, digital cameras, and DVD players. Another example of an embedded system is a washing machine.
