LinkSVP
In order to facilitate users to develop products in the field of machine vision and Al, we have developed the LinkSVP framework to simplify the upstream and downstream development processes and allow developers to focus on core algorithms. At the same time, several sample programs are made to help users get started easily. We provide tools optimized for embedded acceleration to run deep learning algorithms even on solutions with NNIE units.

development environment

We have cross-compiled common third-party libraries and placed them in the virtual machine, which is convenient for users to develop and use.

open source software

In order to demonstrate the basic capabilities of the evaluation board and make it easier for users to fully evaluate the solution before starting development, we have produced an "encoder system" that displays all the interface capabilities and encoding and decoding performance of the solution in the form of a general-purpose encoder. The product is completely open source, including the main program source code, file system, web page source code, etc.

If the user's target product is similar to the open source product, it can be modified directly on the basis of the source code of the product.
