Abstract

The invention discloses a scientific-oriented, 64-bit flow processor chip which includes scalar processing core as the main processor that is responsible for the executive of the scalar procedure and the scheduling of flow processor core. On-chip memory and controller have the 64-bit scalar processing core and interface between 64-bit flow processing core and outside world and store data and instructions, and the network interface is the communication interface to other processor of the 64-bit scalar processing core and 64-bit flow processing core. The 64-bit scalar flow processing core includes flow controller, calculated group, instruction buffer, computing cluster controller, data buffering and data buffer controller.

Description

technical field [0001] The invention mainly relates to the field of microprocessor design, in particular to a 64-bit stream processor chip for scientific calculation. Background technique [0002] For a long time, the improvement of microprocessor performance (the number of operations that can be processed per unit time, generally measured by MIPS or FLOPS) mainly depends on two factors: clock frequency and parallelism. In recent years, due to factors such as power consumption and signal integrity, the continuous increase in clock frequency has shown a slowing trend, with an annual increase of only 6%. Correspondingly, the improvement in performance has dropped from 52% in the 1990s to about 20%. Exploitation of parallelism has reemerged as a major approach to increasing microprocessor performance. The so-called parallelism refers to the average number of operations that can be performed simultaneously per clock cycle. Instruction Level Parallelism (ILP for short), Data L...
