Disclosed aspects relate to facilitating system design based on unified chip specification. It can be determined based on the system design that a first interface of a first chip is to be connected to a second interface of a second chip. Then a first configuration of the first interface and a second configuration of the second interface are determined based on a unified specification. The unified specification at least specifies configurations of a plurality of chip interfaces for respective usages. A hardware design may be automatically generated based on the first and second configurations. The hardware design may include a hardware-level connection between the first and second interfaces.

System design based on unified chip specification

A method for controlling a pipeline-based processor. The method includes determining a change in a workload. The method also includes activating or shutting down, by at least one controller circuit, one or more of the plurality of enhanced pipeline stages based on at least one corresponding enhanced stage priority level of the one or more of the plurality of enhanced pipeline stages and requirements for performance of the workload. The method additionally includes activating or shutting down, by the at least one controller circuit, one or more of the plurality of enhanced modules of the particular pipeline stage based on at least one corresponding priority level of the one or more of the plurality of enhanced modules of the particular pipeline stage and the requirements for the performance of the workload.
