Comp 541 Wrap Up! Montek Singh Apr 27, 2018

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

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

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

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

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

So, what did we learn this semester?

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

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

Final Exam? Grades? We will try to grade HW3 by Monday, and Final Projects next week Final Exam is on Thu, May 3, 12-3pm

Final Exam Material covered: Exam policy: Schedule: Everything, but more emphasis on post-midterm material Easily 40-60% of the points may be for material covered by Lectures 11, 15 and 16 single-cycle / multi-cycle / pipelined CPU Exam policy: Open-book, open-notes, calculator allowed Laptop allowed for: accessing class website, Verilog references, and basic calculator functions Schedule: Exam time: Thu, May 3, 12-3pm, FB007 Final Grades: By May 6
