Entree: the first automatic design flow for deploying the inference of large Decision Tree (DT) ensembles on FPGA-enabled embedded devices

Entree generates hardware accelerators for arbitrarily large DT ensembles on embedded-class heterogeneous Systems-on-a-Chip (SoCs) mounting an FPGA.

Its design flow automatically instantiates a template hardware architecture that exploits the FPGA’s partial dynamic reconfiguration capabilities to host an arbitrarily numerous DT ensemble on it.
