Today's digital avionics systems leverage the use of the Embedded COTS (Commercial Off The Shelf) hardware to fit the need of small form factor, low power, reduced time to market and reduced development time with efficient use of DO-254 for compliance of product. COTS modules are entering in digital avionics systems such as COM (Computer On Module)/SOM (System On Module)/SIP (System In Package) with huge advancement in semiconductor and packaging industry. In today's scenario COTS are very useful for DAL (Development Assurance Level) C and below as the efforts on compliance for DAL A and B are huge.
This paper proposes to use these for DAL A and B as well, where one can get enormous benefit on efforts of compliance and time to market.
This paper makes an attempt to explain the current scenario of the Embedded COTS usage in Avionics Systems. This paper also brings the study of the selection process of Embedded COTS along with the important selection parameters, constraints, challenges and guidelines.
This paper also makes an attempt to visualize next generation of COTS along with its advantages and disadvantages.
This paper finally brings out probable thoughts and outcome of study of embedded COTS which can be leveraged for using embedded COTS in various Avionics Systems.
