2. … to improve speed? … to improve energy efficiency?
What else can we do?
… to improve speed?
… to improve energy efficiency?

3. Multicore/multiprocessor
Use more than one processor = multiprocessor
called multicore when they are all on the same chip

4. GPUs for data-intensive tasks
Originally developed for graphics
Now rapidly gaining importance for general-purpose computing
Main advantages
Massively data-parallel
Fast memory architectures
More computation for less energy consumption

5. Nanotechnology Nanoelectronics DNA based self-assembled electronics
Use DNA to fabricate tinier transistors than possible today using laser/lithographic techniques

6. Energy-efficient design
Many many research directions…
A new and very interesting one is “energy harvesting”
Smart home: Internet-of-Things

7. So, what did we learn this semester?

8. What we learnt this semester
You have learnt:
hierarchically decompose a complex spec
use state-of-the-art software tools for hardware design
understand concurrency
develop concurrent system specs and implementations
test a concurrent system for correctness
evaluate performance
projects:
how data and instructions are represented
how arithmetic and logic operations are performed
how ALU and control circuits are implemented
how registers and memory are implemented
how I/O is integrated with the CPU
assembly programming

9. Where to go from here? Courses you can take in the future:
COMP 740: Computer Architecture [grad]
Course in Mobile Computing / Internet-of-Things
Course in VLSI Design
