Description:
You are to implement a very simple disassembler. Prompt for the starting and ending addresses of loaded HC11 code that only uses the following instructions:
Instruction
Any branch instruction
ADDA Immediate, direct, extended mode only
DECA Inherent only
INCA Inherent only
JSR Direct, extended mode only
LDA Immediate, direct, extended mode only
LSLA Inherent only
LSRA Inherent only
RTS
STA Direct, extended mode only
SUBA Immediate, direct, extended mode only
SWI
Instruction Allowable modes Class
Any branch instruction Relative REL
ADDA Immediate, direct, extended GEN
DECA Inherent INH
INCA Inherent INH
JSR Direct, extended NOIMM
LDAA Immediate, direct, extended GEN
LSLA Inherent INH
LSRA Inherent INH
RTS Inherent INH
STA Direct, extended NOIMM
SUBA Immediate, direct, extended GEN
SWI Inherent INH
Output a dissembled instruction and pause until the user strikes the space bar. Continue in this fashion until reaching the ending address. Your main processing loop should advance the program counter as you obtain and disassemble instructions. When you read an opcode word, you must identify the mnemonic and the addressing mode. When the mode is REL, you have the read the 8-bit offset that is relative to PC+2, where PC is the address of the opcode byte. Add the offset to PC+2 using signed arithmetic
Deliverables:
1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request.
3) Complete ownership and distribution copyrights to all work purchased.
Platform:
This program needs to run on the motorola mc68hc11 microcontroller and be programed in C. I have all the libraries and assemblers if you need them as well.
Must be 100% finished and received by buyer on:
May 5, 2003 EDT
Deadline legal notes: All times are expressed in the time zone of the site EDT (UT - 5). If the buyer omitted a time, then the deadline is 11:59:59 PM EDT on the indicated date.
