- 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).

+ The next quiz is planned on Nov 15.
+ Homework3 [SoftCPU](https://hackmd.io/@sysprog/2022-arch-homework3) is out.
+ Next week, we will review all the assignments.
- Recent [rv32emu](https://github.com/sysprog21/rv32emu) changes
+ More descriptions about system calls. See [docs/syscall.md](https://github.com/sysprog21/rv32emu/blob/master/docs/syscall.md)
+ Implement `clock_gettime` system call, so that you can call `gettimeofday`/`clock_gettime` in C programs.
+ Implement [user-level counters](https://github.com/riscv/riscv-isa-manual) for getting CPU cycle counts in RISC-V programs. See [tests/perfcounter](https://github.com/sysprog21/rv32emu/tree/master/tests/perfcounter) for sample usage.
+ Better experiences while [running Doom and Quake games](https://github.com/sysprog21/rv32emu/blob/master/docs/demo.md). You can resize the window and use mouse properly.
+ More test programs: jit-bf (JIT assembler for RISC-V), coro (a simple coroutine implementation for RISC-V), mandelbrot (an ASCII-based renderer for Mandelbrot Set, colorized), richards (an operating system task scheduler simulation benchmark), and chacha20 (stream cipher)
+ More comments in source files.
+ Next week, we will continue reviewing all the assignments.
+ Quiz 4 is scheduled next week.
