What processor architecture is in a 230GMULps KPU design?

While AI products are becoming popular recently, when looking at the "Seeed Studio Grove AI HAT for Edge Computing Artificial Intelligence Board" it mentions a RISC-V, a 230GMULps 16-bit KPU (Neural Network Processor), a FPU, etc.

What is this "230GMULps"? What could be the processor architecture in it if it can be illustrated by an example?

Update: I initially thought of a specific model. As comments indicated that it is the number of multiplications, so I updated the question to ask for an example architecture.
