Youwilldesignandbuildacircuitwhichanalyzesmachinecodeinstructions,i.e.astaticanalyzer

Yourcircuitwillreadmachine-languageinstructionsfromaROMcomponentandprovideacountofthenumberoftotal instructions in a program and also count the different instruction types:

1. DP(add,sub,mov,cmp) 2. MEM(ldr,str)
3. B(b,bCC)
4. MUL

5. BX

Todeterminetheendofaprogram,yourcircuitwilllookforaninstructionmarker.Themarkerwillbeaddr0,r0,#0.Note this is a valid instruction, but one that is unlikely to appear in normal code. You must add this marker at the end of each program you will analyze.

Youonlyneedtosupportprogramsthatcontainupto256instructions(includingthemarker).

YoucanusetheDigitalcomponents:multiplexors,encoders,decoders,gates,splitters,andwires.Youmustsupplyall other components yourself including: adders, registers, counters, instruction storage, and analyzer.

6. Testinput:Yourinstructionstoragewillcontainthemachinecodeforfib_rec_s,find_max_s,quadratic_s,andsum_array_s, as generated by

 $ objdump -d file.o | python makerom3.py > file_rom.hex
