// 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.
