microprobe.target.Target

class Target(isa, env=None, uarch=None)

Bases: microprobe.utils.misc.Pickable

Class to represent a code generation target.

A target is defined by the architecture, the microarchitecture implementation and the generation environment. The Target object provides a common interface to all the architecture/microarchitecture/environment specific methods using a facade software design pattern. Therefore, all the references to target related properties should go through this object interface in order to minimize the coupling with the other modules (code generation, design space exploration, …).

__init__(isa, env=None, uarch=None)

Create a Target object.

Parameters:

• isa (ISA) – Architecture (i.e. Instruction Set Architecture)
• env (Environment) – Environment (default: None)
• uarch (Microarchitecture) – Microarchitecture (default: None)

Returns:

Target instance

Return type:

Target
