The massively parallel structure of neuromorphic circuits leads to efficient computations of complex problems. Depending on the learning process, the interconnections between neurons are differently weighted. This functionality can be modeled by memristive devices * nonlinear resistors with memory.
These devices in nanotechnology contain always parameter spread, which makes reproducible analyses hard. Additionally, some neuromorphic applications may need a desired but not realizable memristive functionality. Simulation models can be used, but they are very time-consuming and even less suited for hardware emulation purposes. Due to these issues, hardware emulators of memristive systems are needed.
Our approach pursues an FPGA implementation of memristive systems based on wave digital principles. This leads to a generic memristive emulator by maintaining the passivity of the analog device.
