§ What do we need to know about I/O devices ? • Are they ready to process CPU’s request? • Where to send the data to be processed by I/O device ? Most I/O devices are not purely digital themselves ... • Not super-interested in controller/device internals for now.. §How are device registers identified? §How is timing of transfer managed?
LC-3 Simulator - w Chargin
Web-based simulator for the LC-3 (Little Computer 3) Upload object files (.obj) and symbol files (.sym) by dragging them onto the box below. You can upload multiple files at once. You must convert any ASCII binary (.bin) or hexadecimal (.hex) files, and assemble any assembly language (.asm) programs, before uploading.
【lc3】汇编实现I/O中断 - CSDN博客
2024年10月5日 · 在lc3中，mio指令是针对特定的i/o设备的，比如in和out指令，它们可以直接与i/o设备进行交互，而mmio指令则是将i/o设备映射到内存，以便使用ld和st指令来读写内存，而不需要使用in和out指令。
3. LC3控制器的设计 — lc3_lab documentation - Read the Docs
在LC3中，Controller的功能为接收上一周期的运算结果，根据上周期的状态生成本周期的状态，最后根据生成的状态查表得到控制信号（微指令），并传送给数据通路和存储器，让其做出对应的工作。 原理如图所示： 其中状态转换以及状态编号在《计算机系统概论》p369 和 p377。 而控制信号（微指令）在 p371-372。 每一个状态对应一个控制信号列表（该表见文末附录），可视为一个二维数组，该二位数组即微指令表。 控制信号：信号长度为49bits，微指令表的容量则为状态 …
The IO-LC1 and IO-LC3 are I/O Expansion Modules that can be used in conjunction with specific Unitronics OPLC controllers. IO-LC1 offers 1 Loadcell input; IO-LC3 module offers 3 Loadcell inputs. Both modules offer 1 PNP (source) input and 2 short-circuit protected PNP (source) outputs with optional setpoint action that is

lc3 评测 | ICS Fall 2022
其中，评测函数需要负责初始化寄存器和（重置每次使用到的）内存的值，具体来说，函数内部可以通过 lc3.r 和 lc3.memory 来访问寄存器数组变量和内存数组变量。

LC3 IO
Polling consumes a lot of cycles, especially for rare events – these cycles can be used for computation. Example: Process previous input while collecting current input. Resume the stopped program as if nothing happened. When ready bit is set and IE bit is set, interrupt is signaled. interrupt signal? Payroll program runs at PL0.
