Simpleton is a minimalist Convey personality that has two custom instructions.  The first increments a value in an AEG register.  The second uses a single memory controller to increment a value in coprocessor memory.
 
Advantages of using Simpleton as the start of your project include:
* It's minimalist
* It's well commented
* The top level module, personality.v is awesome:
** The port declaration is only 50 lines and no longer scary (cae_pers.v is >150 lines)
** It wraps the memory controller interfaces in to unpacked arrays so you can easily use generate loops
** It hides unnecessary instruction decode and clock logic
** It gets rid of the CSR interface (because, honestly, you weren't going to use it anyway)

Overview

Simpleton is a minimalist Convey personality that has two custom instructions. The first increments a value in an AEG register. The second uses a single memory controller to increment a value in coprocessor memory.

Advantages of using Simpleton as the start of your project include:

  • It's minimalist
  • It's well commented
  • The top level module, personality.v is awesome:
    • The port declaration is only 50 lines and no longer scary (cae_pers.v is >150 lines)
    • It wraps the memory controller interfaces in to unpacked arrays so you can easily use generate loops
    • It hides unnecessary instruction decode and clock logic
    • It gets rid of the CSR interface (because, honestly, you weren't going to use it anyway)
