10. Architecture Memory –Separate memory for Instructions & Data –Data Memory currently in block ram 768x16 + 256x16 = 1024x16 Block ram is fast –Instruction memory currently in flash 64K x 16 Finite state machine reads from flash Slowest component limits clock to 10Mhz (20Mhz if we are tricky)

11. Architecture Pipelining –Not part of baseline, but we want to do it –No stalls waiting for memory because of separation –Followed MIPS (pipeline work has already been done) –Clock limited to 10Mhz –Data forwarding unit avoids data hazards –Software avoids jump/branch hazards

20. Nibbles

22. Pipelining In pipelined systems jump require “bubbles” to execute correctly This can be implemented in assembly by inserting NOPs

23. Code implemented jumps MOVI $tmp, 1 CMPI $regb, 0 BNE _ifgrow STOR $rega, $tmp //IF (grow == 0) //Move 1 into *head

25. What’s next Make your own Game! TronMillipedeTetris?!

26. Testing Best tests Should be in the writing. ->Write using “Test First” method Second stage “Black Box” testing. Optional Third Stage “White Box” testing.
