Tiny iCAP controller with single-event upset fault injection

Abstract

The invention provides a micro ICAP controller having a single event upset fault injection function. PicoBlaze acts as the master control unit of the ICAP controller to receive the function request orfault injection request instruction from a reconfiguration system and then control an ICAP port and a frame fault detection unit to work; the structure of the ICAP controller is composed of an RAM, the PicoBlaze controller, the ICAP port and the frame detection unit; the PicoBlaze controls the whole process of reconfiguration and fault injection; the RAM is controlled by the PicoBlaze controllerand used for storing the configuration frame data; the frame detection unit is used for verifying the frame data in the configuration process; and the PicoBlaze receives the function instruction of the reconfiguration system in the configuration process and analyzes the function instruction and then completes the corresponding function. The ICAP controller fault injection function does not requireadditional resource and does not influence operation of the reconfiguration system, and the effect is close to the real environment.

Description

Technical field: [0001] The present invention has a miniature ICAP {ICAP is an abbreviation of Internal Configuration Access Port (ICAP) internal configuration port} controller with a single event flipping fault injection function, which is a controller used for reconfiguration of partial bit files in the process of dynamic reconfiguration , in particular a configuration port controller with a real-time online single-event flip fault injection function, which realizes the FPGA online fault injection and reconfiguration functions, and belongs to the field of computer technology. Background technique: [0002] Currently, more and more FPGAs are used in embedded systems and high-speed operating environments, thanks to the flexible programmable features of FPGAs, coupled with its reconfigurable features, the role of FPGAs in industrial control is becoming more and more important. bigger. The reconfigurable feature allows users to dynamically change some internal configuration i...
