Study Notes

System Specification and Decision Making in System Design

System Specification is the controlling document in a project that includes product function, performance requirements, system interface, error handling procedures, and design constraints.
Microprocessor tasks and product interaction with the environment should be identified and described in the system specification.
A user's manual can be a useful way of providing specifications on how the product will interact with its environment.
Design engineers must make important decisions without outside help in the system design phase, including build or buy ready-made parts, choice of microprocessor, and hardware or software implementation.
Using commercially available systems is good practice for beginners in early design because of known cost and performance.
The choice of microprocessor is important and should consider software availability, quantity availability, and experience of others.
Development tools, including data sheets, programmer's guides, and software development tools, should be adequate to reduce development time and make programming easier.
The processor should be fast enough and have enough addressing space to support the application at hand.
Processors can be programmed to perform a wide variety of tasks, but there is still a need for some electronic hardware design in the interface.
There are software/hardware trade-offs in achieving tasks that interact with external environment and devices, with cost as the deciding factor.
Hardware implementation has a component cost but requires less development effort and has higher processing speed.
Software implementation has no component cost but may involve a large amount of development effort and is generally slower in operation.
