Despite September 17th being a national holiday for Mid-Autumn Festival, our class will continue as scheduled, and students are required to complete an online quiz. For information on how to participate and access the remote class, please refer to this website.
The first assignment, consisting of RISC-V assembly programming, will be given next week.
Quiz1: C programming, bit-wise operations, number representation, floating-point / Solutions
Week 3 (Sep 24): RISC-V
Announcement:
Quiz2 is scheduled on Oct 1: Due to the possibility that the classroom capacity may not accommodate the number of enrolled students, additional classrooms may be arranged as test venues. Please make sure to check this page on the evening of September 30th for related announcements.
Due to the impact of Typhoon Krathon, Quiz 2 will be conducted online instead of in-person. Please refresh this web page to obtain the latest information on how to participate in the online quiz and attend the course remotely.
Access the live-streamed course on YouTube. Watch the live stream carefully: Quiz 2 participation instructions will be provided during the broadcast.
Quiz 3 is scheduled for Oct 22 and will cover RISC-V assembly programming, software optimizations, instruction encoding, sequential logic, and combinational logic.
Yes, you can implement a few logic-like elements without electricity.
Logic gates are primarily implemented using diodes or transistors acting as electronic switches, but can also be constructed using vacuum tubes, electromagnetic relays (relay logic), fluidic logic, pneumatic logic, optics, molecules, or even mechanical elements. Now, most logic gates are made from MOSFETs (metal–oxide–semiconductor field-effect transistors).
sequential logic is a type of logic circuit whose output depends on the present value of its input signals and on the sequence of past inputs, the input history.
Constructing Hardware in a Scala Embedded Language (Chisel) is an open-source hardware description language (HDL) used to describe digital electronics and circuits at the register-transfer level that facilitates advanced circuit generation and design reuse for both ASIC and FPGA digital logic designs.
The next homework assignment will be given out next week, along with Quiz 4. Please review last year’s homework to get familiar with the procedure and expectations.
This semester, we will conduct 7 quizzes. Out of these, the best 4 will be selected for grading purposes.
The instructor will submit the grades on the school’s designated deadline (Jan 24, 2025) for grade registration. This means that students will have ample time to dedicate to the final project assigned in this course.
Lockstep systems are fault-tolerant computers that simultaneously perform identical operations in parallel. Borrowed from military marching terminology, these systems use redundancy to detect and correct errors. With two systems (dual modular redundancy), errors can be identified, and with three systems (triple modular redundancy), errors can be automatically corrected through majority voting.
Regarding the final project, students may form groups of 1 to 3 members (the project’s difficulty will depend on the group size and members’ backgrounds). Please refer to last year’s projects for reference and send an email to jserv.tw@gmail.com, specifying your group members and proposed project topics (you may suggest multiple topics, with the final decision made by the instructor).
Due to the instructor’s significant involvement in a confidential project, there has been limited participation in this course. Consequently, the instructor proposes a modification to the course grading structure.
The new breakdown will be as follows: Quiz (30%), Homework (30%), Final/Term Project (25%), and an additional “Base” component (15%). This “Base” component ensures that each student’s starting score is at least 15%.
Quiz7 is scheduled on Jan 7, 2024
rv32emu introduces tier-1 JIT compiler to accelerate RISC-V simulation.
Execute make ENABLE_JIT=1 clean all and then run build/rv32emu build/smolnes.elf to play NES games.
