摘要： Systems and methods are disclosed to automatically generate a processor architecture for a custom integrated circuit (IC) described by a computer readable code. The IC has one or more timing and hardware constraints. The system extracts parameters defining the processor architecture from a static profile and a dynamic profile of the computer readable code; iteratively optimizes the processor architecture by changing one or more parameters until all timing and hardware constraints expressed as a cost function are met; and synthesizes the generated processor architecture into a computer readable description of the custom integrated circuit for semiconductor fabrication.

摘要： Systems and methods are disclosed to automatically generate a custom integrated circuit (IC) described by a computer readable code or model. The IC has one or more timing and hardware constraints. The system extracts parameters defining the processor architecture from a static profile and a dynamic profile of the computer readable code; iteratively optimizes the processor architecture by changing one or more parameters of the architecture in a hierarchical manner until all timing and hardware constraints expressed as a cost function are met using an architecture optimizer (AO); and synthesizes the generated processor architecture into a computer readable description of the custom integrated circuit for semiconductor fabrication.

摘要： Systems and methods are disclosed to automatically generate a custom integrated circuit (IC) design by receiving a specification of the custom IC including computer readable code to be executed by the custom IC; generating an abstraction of the IC as a system, processor architecture and micro-architecture (SAMA) representation; providing the SAMA representation to a data model having at least an architecture optimization view, a physical design view, and a software tool view; optimizing the processor architecture by iteratively updating the SAMA representation and the data model to automatically generate a processor architecture uniquely customized to the computer readable code which satisfies one or more constraints; and synthesizing the generated architecture into a computer readable description of the custom integrated circuit for semiconductor fabrication. The foregoing can be done with no or minimal human involvement.
