IntroductionWhat is CAPC?
A processor that can perform 15 machine instructions
Development tool – Logic WorksDesign schedule
Component integration
The Initial Clock
“Heart of the system”8-signal clockFetch cycle / Execute cycle
Registers12-bit registers – PC, MAR16-bit registers – MBR, G, KB, X, Y4-bit register – IR
Data Bus & RAM
Data transferred along 16-bit data bus Original design – Lab 3 – Write to MBR Second design – Write to RAM Directly
Read Only Memory (PROM)
Storing program in PROM Updated RAM / PROM hybrid
PROM is 1/16k RAM is 4k, but first 1/16k is redundant 000000000000 – 000000111111
PROM >= 000001 000000 RAM
Arithmetic Logic Unit
6 operations SEND_NOT,
SEND_2X, SEND_ADD, SEND_OR, SEND_XOR, SEND_AND
X and Y data input registers; no Z register
Keyboard
A hexadecimal keyboard that utilizes two registers to send data
Integrating Components
Machine Instructions– what “And gate” and “OR
gate” can do
Control Unit
Three Revolutions Is lab8’s control unit producing
correct signals all the time? Can we restart the clock? How do we prevent the slight chance
of faulty signal?
CAPC-SP
What does SP stand for? Self-Present version of CAPC Introducing the following devices
Hex-ASCII translatorMachine-Assemble translatorDevice monitor
The first two are simply PROMs and the last one is the combination of PROM and encoder.
Conclusion
Tech3 develops extreme CAPC Can perform super computations “Einstein” class system
