class dau_core.capabilities.DeviceCapabilities[source]¶

What a probed device advertises.

operators are hardware capabilities — opcodes some tile executes in HDL. host_operators are protocol-level capabilities the host derives from hardware results (AVERAGE = host divide of SUM/COUNT); they must never be submitted to the device as operations.
