From 3cff7429e776c0879aa5a60492e3314694decb45 Mon Sep 17 00:00:00 2001 From: mbaret <55580676+mbaret@users.noreply.github.com> Date: Wed, 19 Aug 2020 17:39:33 +0100 Subject: [PATCH] [BYOC][ETHOSN] Introduce the Ethos-N BYOC integration (#6222) * [BYOC][ETHOSN] Introduce the Ethos-N BYOC integration This is the first of 3 PRs to introduce the Ethos-N integration into TVM via the BYOC framework. It adds support for partitioning and compiling for the Ethos-N77 target with CPU fallback for unsupported operators. Additionally, runtime support is added in the form of an Ethos-N runtime module. In this initial PR, only quantized concatenate and split are supported with follow-up PRs adding support for many further operators.
