Hi Chris, I remember doing a design for a PDP-11 using the 2901 during my architecture class back in the 1970's.

If you understand the ARM core well enough, it is probably possible to build one using the bit-slice technology, but you are going to have a lot of work to implement all of the details.

Would the 2901 lend itself to emulate something like MSP430 with its 16 registers?

I think I would approach this differently and use an FPGA to mimic the ARM7, unless you just happen to have the AMD 2901 bit slicer around. So why did you pick this? Maybe an 8501 would be better since it is widely used and fairly well known. ARM7 just seems too variable and the designs are licensed and hard to come by. Just my own thought here. But [mention:753dd297e7584712840f1c3de8add506:e9ed411860ed4f2ba0265705b8793d05] you may have your own set of assumptions. Care to elaborate?
