INTEGRATED CIRCUIT WITH CHIP-LEVEL SERIAL POWER DOMAINS, AND CIRCUIT BOARD HAVING THE SAME

摘要

A multi-core processing integrated circuit (IC) chip includes a plurality of processing unit groups. Each processing unit group includes a group voltage input terminal, a group voltage ground terminal, and one or more processing units, each processing unit having a voltage input terminal and a voltage ground terminal. The plurality of processing unit groups includes a bottom-level processing unit group and a top-level processing unit group. The group voltage ground terminal of the bottom-level processing unit group is connected to a ground pin of the multi-core processing integrated circuit chip. For each processing unit group other than the bottom-level processing unit group, the group voltage ground terminal of the processing unit group is connected to the group voltage input terminal of a previous-level processing unit group within the plurality of processing unit groups. The group voltage input terminal of the top-level processing unit group is connected to a voltage power input pin of the multi-core processing integrated circuit chip.
