Description

technical field

[0001] The invention relates to an internal communication node of a microprocessor chip, in particular to an on-chip router supporting single-cycle message forwarding. Background technique

[0002] After nearly 30 years of development, semiconductor technology has the ability to integrate billions of transistors on a single chip, which has created a steady stream of power for the development of high-performance microprocessors, but also brought new opportunities to chip design with challenges. At present, regarding how to utilize numerous transistor resources, the industry generally realizes that "many-core" processors, as the most effective means to improve computing performance, will become the mainstream development trend of future microprocessor structures. In this context, a single chip integrates hundreds of processor cores, and the performance bottleneck of the microprocessor will be transferred to the interconnection and communication between many pr...
