Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] The present invention proposes a set of method and system for optimizing and reducing data transmission delay between instructions, the core technology of which lies in the non-speculative lookahead firing selection mode. In the mode proposed by the present invention, the downstream node confirms the launch schedule of the command in advance, and notifies the upstream node of the "Ready" information in advance, so that the downstream node waiting to tran...

Abstract

The invention provides a method and a system for optimizing a data transmission delay of a data stream framework. The method comprises the following steps of S1: recording a historical behavior corresponding to each instruction slot in an upstream node and a downstream node, and predicting whether the downstream node can send idle state information to the upstream node or not according to the historical behavior; S2: if the downstream node can send the idle state information to the upstream node in advance, storing instruction slot data in the nodes to a prejudgment sending part, wherein the instruction slot data contains a hop count delay field, which is used for representing a hop count x required for enabling a target operand of the upstream node to reach an original operand of the downstream node at a highest speed; and S3: according to the hop count delay field, sending the instruction slot data stored in the prejudgment sending part to the upstream node by the downstream node after X cycles.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a method and system for reducing data transmission delay. Background technique [0002] With the development of computer architecture, domain-specific computer architecture has become the main development trend. When oriented to a specific application, the special-purpose structure uses the application characteristics to optimize the structure accordingly, so as to better exert the computing performance of the hardware. In the field of high-performance computing, data flow computing is an important branch of domain-specific computing structures, and data flow computing has shown good performance and applicability. The basic principle of data flow instruction execution is: all source operands are ready, and the downstream nodes have free data slots to receive data, then the instruction can be sent to the execution unit for operation and execution. In the data flow comp...
