PPCBug
Because PPCBug is
The PPCBug is similar to previous Motorola firmware debugging packages (for example, MVME147Bug, MVME167Bug, MVME187Bug), with differences due to microprocessor architectures. These are primarily reflected in the instruction mnemonics, register displays, addressing modes of the assembler/disassembler, and the passing of arguments to the system calls.
Memory Requirements
PPCBug requires a maximum of 768KB (maybe less) of read/write memory (that is, DRAM). The debugger allocates this space from the top of memory. For example, a system containing 64MB ($04000000) of read/write memory will place the PPCBug memory page at locations $03F80000 to $03FFFFFF.
PPCBug Implementation
PPCBug is written largely in the C programming language, providing benefits of portability and maintainability. Where necessary, assembly language has been used in the form of separately compiled program modules containing only assembler code. No
Physically, PPCBug is contained in two socketed
