Data processing chip, manufacturing method thereof and data processing system

The invention provides a data processing chip, a manufacturing method thereof and a data processing system, aiming at solving the technical problems that high-speed transmission of data cannot be ensured based on limited memory bandwidth and the computing power requirement is difficult to meet. The data processing chip includes: a first die including an arithmetic unit; the second crystal grain and the first crystal grain are stacked, and the second crystal grain comprises a buffer which is coupled with the arithmetic unit through bonding; wherein the buffer is configured to buffer the transmitted data when the arithmetic unit and the host carry out data transmission or when the arithmetic unit and the memory carry out data transmission. Therefore, a higher bandwidth is provided for data transmission, and the bandwidth demand of the system is reduced while high computing power is realized. 本公开基于有限的内存带宽无法保证数据的高速传输，难以满足算力需求的技术问题，提供一种数据处理芯片及其制造方法、数据处理系统。数据处理芯片包括：第一晶粒，包括：运算器；第二晶粒，与第一晶粒堆叠设置，包括：缓存器，缓存器通过键合与运算器耦接；其中
