They are collectively referred to in this manual as the
PowerPC board
or
board
.
The debugger includes:
Commands for display and modification of memory
Breakpoint and tracing capabilities
Assembler and disassembler useful for patching programs
Various PPCBug routines that handle I/O, data conversion, and
string functions are available to user programs through the System
Call handler.
Because PPCBug is command-driven, it performs its various
operations in response to user commands entered at the keyboard.
Comparison with other Motorola Bugs
The PPCBug is similar to previous Motorola firmware packages
(e.g., MVME147Bug, MVME167Bug, MVME187Bug), with
differences due to microprocessor architectures. These differences
are primarily reflected in the instruction mnemonics, register
displays, addressing modes of the assembler/disassembler, and
argument passing to the system calls.
PPCBug Implementation
PPCBug is written largely in the C programming language,
providing benefits of portability and maintainability. Where
necessary, the assembly language has been used in separately
compiled program modules that deal with processor-specific
issues. No mixed-language modules are used.
Physically, PPCBug is contained in two socketed 32-pin PLCC
Flash devices that together provide 1MB (256KB words) of storage.
PPCBug uses the entire memory contained in the two devices.
