Overview • The software design cycle • Designing differences • Code differences • Test differences
In general... • They are the same • All programs have: • Inputs • Processing/Decisions • Outputs • Always use the Software Design Cycle
Software Design Cycle • Specification • Design • Code • Test http://rabatech.com
Specification • Understand the Requirements • The same words mean different things to different people • As a group, what does the following mean:The program must respond quickly to input. • Write down the Requirements • Once you know what you plan to do (with numbers) write it down!
Design • Decide the ‘best approach’ to meet your requirements • Hardware • Programming Language • Customer Education(Change the Requirements)
Coding Embedded PC Application Abstracted Hardware Plenty of Resources Has an Operating System • Closer to the Hardware • Use native data types • Fewer System Resources • No Operating System • More efficient algorithms • Higher frequency = higher power
Testing Embedded PC Application Usually simple to get a basic debug output Can be very sophisticate testing • Testing must be planned in • Usually a simple interface • Often involves extra hardware
Other big differences • Take a few minutes and talk in small groups. I’ll be asking one group to give some of the ideas they came up with.
Things to Remember • There are parallels between embedded and PC programming • When coding embedded, it is better to use native data types
