Great Ideas of Computer Architecture (Machine Structures)</h1> </div> </div> <p><strong>Catalog Description:</strong> The internal organization and operation of digital computers. Machine architecture, support for high-level languages (logic, arithmetic, instruction sequencing) and operating systems (I/O, interrupts, memory management, process switching). Elements of computer logic design. Tradeoffs involved in fundamental architectural design decisions. </p> <p><strong>Units:</strong> 4</p> <p><strong>Prerequisites:</strong> COMPSCI 61A, along with either COMPSCI 61B or COMPSCI 61BL, or programming experience equivalent to that gained in COMPSCI 9C, COMPSCI 9F, or COMPSCI 9G.</p> <p><strong>Credit Restrictions:</strong> Students will receive no credit for COMPSCI 61C after completing COMPSCI 61CL. </p> <p><strong>Formats:</strong><br> Summer: 6.0 hours of lecture, 2.0 hours of discussion, and 4.0 hours of laboratory per week<br /> Fall: 3.0 hours of lecture, 1.0 hours of discussion, and 2.0 hours of laboratory per week<br /> Spring: 3.0 hours of lecture, 1.0 hours of discussion, and 2.0 hours of laboratory per week</p> <p><strong>Grading basis:</strong> letter</p> <p><strong>Final exam status:</strong> Written final exam conducted during the scheduled final exam period</p> <hr> <p><strong>Class Schedule (Fall 2024):</strong> <br> CS 61C – MoWeFr 10:00-10:59, Dwinelle 155 – <a href="/Faculty/Homepages/garcia.html">Dan Garcia</a>, <a href="/Faculty/Homepages/peyrin.html">Peyrin Kao</a><p><strong>Class Schedule (Spring 2025):</strong> <br> CS 61C – MoWeFr 15:00-15:59, Valley Life Sciences 2050 – <a href="/Faculty/Homepages/yanlisa.html">Lisa Yan</a> <p><a href="http://inst.eecs.berkeley.edu/~cs61c">Class homepage on inst.eecs</a></p> <hr> <p><strong>Department Notes:</strong> <p> Starting this semester, Fall 2010, we are reinventing CS61C, starting with a blank page as to what makes sense to teach of computer architecture and hardware in 2010 that will give a solid foundation on the topic on which to build that should last for decades. </p><p> Rather the be something of a catch-all, as in the past, the goal is to learn the great ideas of computer design and implementation: </p><ul> <li> Memory Hierarchy (e.g., Caches) </li><li> Thread Level Parallelism (e.g., Multicore) </li><li> Data Level Parallelism (e.g., MapReduce and Graphical Processing Units or GPUs) </li><li> Instruction Level Parallelism (e.g., Pipelining) </li><li> The Transistor and its rate of change (e.g., Moore's Law) </li><li> Quantitative Evaluation (e.g., GFLOPS, Clocks Per Instruction or CPI) </li><li> Layering of Hardware Levels of Abstraction (e.g., AND gates, Arithmetic Logic Unit or ALU, Central Processing Units or CPU) </li><li> Compilation vs. Interpretation (e.g., C compiler, Java interpreter) </li><li> Hardware Instruction Set Interpretation (e.g., instructions as binary numbers) </li></ul> <p> The idea is to go over the big ideas at a higher level in the first two-thirds of the course, and then go back in more depth in the last third of the course. </p><p> We use a running example through the whole course to illustrate the ideas, and will be the basis of a programming contest in the last third of the course to see who can make the fastest version running on the latest multicore hardware. </p><p> We use the C programming language and MIPS assembly language to demonstrate these great ideas. The course closely follows the Patterson and Hennessy textbook supplemented by material on the C programming language. A sample week-by-week outline follows. </p><ul> <li>1 - Introduction - Mobile Client vs Cloud Server </li><li>2, 3 - C programming language vs MIPS assembly language </li><li>4 - Computer Components and Compilation vs Interpretation </li><li>5 - Quantitative Evaluation </li><li>6 - Memory Hierarchy </li><li>7 - Thread Level Parallelism </li><li>8 - Data Level Parallelism </li><li>9 - Transistors and Logic </li><li>10 - Layers of HW Abstraction </li><li>11 - Instruction Level Parallelism </li><li>12 - In More Depth: Cache associativity, Cache coherence, Locks </li><li>13 - In More Depth: Illusion of machine to yourself - Virtual Memory, Virtual Machines </li><li>14 - In More Depth: Dependability via Redundancy - Error Correcting Codes, Redundant Array of Inexpensive Disks </li><li>15 - Contest Results and Conclusion </li></ul> <p>Coursework will involve weekly two-hour in-laboratory exercises designed to learn the big ideas by doing experiments.</p></p> </div> </main> <footer
