FOCUSED APPLICATION

• HARDWARE IS OPTIMISED FOR
• INPUT / OUTPUTS SPECIFIC TO APPS
• MEMORY AS NEEDED BY APPS
• SOFTWARE OPERATING OFF THE ROM OR RAM
• CHIPS USED FOR OPTIMAL POWER CONSUMPTION
• COMPACT FOOT PRINT

HARDWARE USER SPECIFIC

• MICROPROCESSOR.
• INPUT OUTPUT TYPES
• ROM TYPE
• RAM TYPE and BACKUP
• ALGORITHMS PROTOCOLS
• NOT OBSOLESCENCE PROOF
• WHY ?

RTOS - ADVANTAGES

• EU APPLICATION FASTER DEVELOPED
• TECHNOLOGY CHANGES IN HARDWARE DONOT DESTABILISE
  SOFTWARE
• SOFTWARE RETESTING AND VALIDATING IS NOT
  ESSENTIAL
• SMALLER APPLICATION SIZE, ROMMABLE CODE
