The document discusses the processor level of design methodology. It introduces the four main groups of components at the processor level: processors, memories, I/O devices, and interconnection networks. Memories include main memory, secondary memory, and cache memory. I/O devices connect the processor to external devices and interrupts are signals that seek the processor's attention, such as program, timer, and input/output interrupts. The conclusion states that processor design is the engineering task of creating a microprocessor and results in a microarchitecture.

8. Interrupts
 An interrupt is a signal from some device or source
seeking the attention of the processor.
Types of Interrupts
 Program
 Timer
 Input / Output
 Hardware failure

9. Conclusion
• Processor design is the design engineering task of
creating a microprocessor a component of computer
hardware. It is a subfield of electronics engineering
and computer engineering. The design process
involves choosing an instruction set and a certain
execution paradigm and results in a microarchitecture.
