- 10. Determine the requirements Design the system architecture Select the OS Choose the Processor and peripherals Choose the Development platform Code the application And optimize Verify the software On the host system Verify the software On the target system
- 11. Functional and non-functional. Multi function or Multi mode system. Size, cost, Weight etc. Selecting the H/W components. Application specific H/W. External interfaces. Input devices. Output devices.
- 12. System architecture depends on, Whether the system is real time. Whether OS needs to be embedded. Size, Cost, Power consumption etc.
- 13. If OS needed we can select, Real time OS (such as RTLinux,Vx Works, VRTX, pSOS, QNX etc.). Non-real time OS ( such as Windows CE, embedded Windows XP etc).
- 14. We can select any one of the following, Microprocessor 8085,8086,Pentium Microcontroller MCS-51,PIC,AVR,MSP430 Digital Signal Processor dsPIC,Blackfin,Sharc,TigerSharc
- 15. The hardware platform. The operating system. The programming language. The development tools.
- 16. Choice of language. Assembly. C language. Object Oriented Languages (C++, Java etc.). • Optimizing the code
- 17. Compile and assemble the source code into object file. Use a simulator to simulate the working of the system.
- 18. Download the program using a programmer device. Use an EMULATOR or on chip debugging tools to verify the software.
- 19. Due to the developments in Micro electronics availability of processors increased. Reduces cost. Increased speed. Reduce Size Reduce Power.
