// Project: Zip CPU -- a small, lightweight, RISC CPU soft core |
// Project: XuLA2-LX25 SoC based upon the ZipCPU |
// |
// Purpose: |
// Purpose: Provide a debugger to step through the ZipCPU assembler, |
// evaluate the ZipCPU's current state, modify registers as(if) |
// needed, etc. All of this through the JTAG port of the XuLA2 board. |
