Abstract

The invention discloses an FPGA-based mapping-oriented network-on-chip verification method and system. The system introduces a mapping-oriented processing platform for application tasks (the processing platform includes three mapping-oriented soft cores) capable of simulating and generating data for application tasks characteristics; and further designed the analog network-on-chip simulation platform - MAENoC, by writing the mapping application data to each node of the analog network-on-chip, and monitoring the running results of the mapping algorithm in the network-on-chip on-line, it can realize the fast simulation evaluation of the application-oriented mapping network-on-chip ; The analog network-on-chip emulation platform—MAENoC is connected in the form of partitions, and the nodes in the area are connected in the form of buses. Using the method based on routing table configuration, different topologies of NoC can be simulated; each node supports multi-pipeline mechanism and virtual channel dynamic reconstruction, and virtualization technology is added to support NoC verification of a large number of nodes.

Description

technical field [0001] The invention relates to the technical field of on-chip network verification, in particular to an FPGA-based mapping-oriented on-chip network verification method and system. Background technique [0002] With the development of artificial intelligence, machine learning / deep learning processors represented by GPU and general-purpose SoC have encountered problems such as long processing time and limited computing resources. Among the indicators in future 5G communications, processor design that requires multiple application scenarios, high concurrency, low power consumption, and "zero" delay brings higher challenges. On the other hand, according to the latest 7nm manufacturing process, 7 billion transistors can be integrated on a fingernail-sized chip. In deep sub-micron, the typical multicore processor system on chip based on the traditional bus design has bottlenecks such as limited bandwidth throughput, poor scalability, difficult global synchronizat...

AI Technical Summary

Problems solved by technology

The existing mapping verification platform has the following problems in the face of future application requirements: 1. Most of the existing NoC simulators are software simulation platforms written based on high-level programming languages, which have the disadvantage of slow speed when facing large-scale NoC simulation

The Booksim software emulator only needs a few simple C codes to realize the source data sending feature, but the clock frequency of the data packet sending module corresponding to the hardware requirements is much higher than the system clock, which does not conform to the real hardware situation

2. The proposed hardware verification platform is mainly aimed at the design and verification of NoC topology architecture, and lacks a NoC verification platform for application mapping

The verification platform of the appeal is limited to the simulation of the network-on-chip architecture, lacks the key simulation for the data characteristics of the application, and is limited to the simulation of network communication, so it cannot combine the content of multi-core processing to restore the working environment of the multi-core system; common hardware emulators The router is designed as a one-stage single-stage form, rather than the current multi-stage pipeline form. It does not support task mapping assignment in the multi-core field, and lacks power consumption and network congestion simulation data related to mapping.
