+* additional specification of and simulation for concepts like a REMAP engine and element width
+overrides which, when implemented also in HDL, will allow hyper-efficient acceleration of many
 fundamental crypto algorithms. (implemented 100% in simulator, allowing 100% successful implementation of Simple-V-PowerISA assembler to be made, but limited budget of 2021-02-051 was insufficient to complete HDL implementation of REMAP and elwidths)
 * a flexible HDL platform (ls2) for implementing a System-on-Chip on an FPGA or ASIC
 
+One catastrophic mistake made by many cryptographic instruction implementations
+is to create over-specific instructions. "multiply by 2 then subtract 5" for example
