Detailed Documentation¶

Base class Target machine representation. Target derives from this class to provide generator information about supported emittors.

Methods¶

virtual bool is_supported() const = 0

checks if target is natively supported

Returns:

true, if supported

virtual code get_snippet() const = 0

finalizes code generation

Returns:

generated kernel binary

virtual size_t get_lanes() const = 0

gets number of lanes supported by target’s vector ISA

Returns:

number of lanes

std::function<std::shared_ptr<Emitter>(std::shared_ptr<ngraph::Node>)> get(const ngraph::DiscreteTypeInfo type) const

called by generator to all the emittor for a target machine

Returns:

a map by node’s type info with callbacks to create an instance of emmitter for corresponding operation type

bool has(const ngraph::DiscreteTypeInfo type) const

checks if emitter for a specific operation is supported

Returns:

true, if supported
