BYOC:Bring Your Own Codegen To TVM

• Implement your own codegen and register it as a Relay backend compiler to support your hardware device/library
• Usefull when hardware already has a well-optimized C/C++ library
• By default only support TVM Relay IR representation,
• Option to implement graph parsers, If using other graph representation

// Codegen example here

• Once custom codegen registered with a tag toTVM Backend, any subgraph annotated with this tag will be offloaded to the hardware

• Example

• Any optimization have to be incorporated in the Codegen, BYOC does not optimze code by default.

• AutoTVM only helps in systematically exploring the search space, by specifying tunable knobs

• Example
