Two controllers for SCAMP3 are shown below.
A controller is required since SCAMP3 has no program counter program memory.
Controller 1
The controller below is based around a Spartan 3 FPGA (Opal Kelly XEM3001)


Controller 2

This controller operates in a similar way to the first controller. However, it is considerably lighter, smaller and has a sub-mW quiescent power consumption.
