Starting a machine learning (ML) application can be challenging, especially when it involves specialized hardware. Fortunately, the Corstone-320 Fixed Virtual Platform (FVP) simplifies this process by allowing you to develop and test ML applications without physical hardware.The Corstone-320 FVP emulation platform offers a powerful foundation for developing advanced ML applications. Learn how to get started with the Corstone-320 FVP, leveraging the Arm ML Embedded Evaluation Kit (MLEK) available on review.mlplatform.org.
Fixed Virtual Platforms are sophisticated hardware simulation models that enable software development and testing without physical hardware. Particularly valuable in the early stages of development, it allows developers to begin working on software long before the hardware is available.
FVPs provide an accurate representation of the final hardware. Ensuring that the software developed and tested on these platforms will perform as expected once deployed on the physical device. This significantly accelerates the development cycle, reduces costs, and mitigates risks associated with hardware dependencies. For additional information, visit Arm Ecosystem FVPs
