Abstract

The invention discloses a route automatic searching and configuring method based on SRIO switching network. The depth-first traversal algorithm is used to access all kinds of devices in unknown SRIO network to find out all nodes in the network, such as general signal processing resources DSP, FPGA, GPP and routing switch chip SWITCH. The invention can search the unknown SRIO network to find the nodes in the system that have completed SRIO initialization, including DSP, GPP, FPGA and SWITCH.

Description

technical field [0001] The invention relates to a method for realizing automatic search and configuration of a serial high-speed bus (SRIO) switching network route based on a software radio system, in particular to automatic search for SRIO switching network topology and calculation and configuration of optimal paths between nodes in the SRIO switching network. Background technique [0002] As a highly integrated signal processing system, the new software radio system adopts advanced technologies such as open architecture, software reconfigurable, and hardware configurable in order to realize the integration of multiple waveforms. Therefore, the number of general-purpose processing resources in the system Generally, there are more than a dozen or even dozens of SRIO networks and ports. The huge number of SRIO networks and ports, and the variety of communication topologies have gradually exposed some problems in SRIO network configuration. [0003] 1) First of all, with the d...
