    CaChars

    Graphics mode console I/O for the TRS-80 Color Computer

    This is an add-on for the CoCo Extended Color BASIC that implements 51x24 and 64x24 text screens. All operation of the BASIC interpreter works naturally. It is developed in 6809 assembly language. It may be assembled with LWTOOLS (http://lwtools.projects.l-w.ca) under Linux, or with Windows cross-assemblers such as Chet Simpson's CASM which is included in RainbowIDE. In order to build a disk image, you will also need the Toolshed utility suite....

    pFFh

    pFFh

    a self-contained development environment for embedded systems.

    pFFh is a programming language that allows you to launch applications on embedded systems safely, quickly and comfortably. pFFh runs on the target system, combining operation as a command interpreter and code compiler. We can say that pFFh behaves like an operating system on the board under development. All pFFh needs is a serial or USB-serial channel to communicate, and through it, receive and process console commands, either from a keyboard or from files sent from a desktop computer. ...

    8-bit home-made computer on Z80 CPU

    This is a renaissance of the "Specialist" micro-computer published in the popular "Modelist-Constructor" magazine issue #2, 1987 by A. Volkov. The original design was used the Soviet i8080A analog - KR580IK80A (KR580VM80A), but this one is based on the Z80A CPU. Postfix "S" in the project name designates a "simple" design.

    Booting-Aids_2_

    Helps you to Boot your Experimental Assembly Language programs

    ...The Memory Sticks have to be formatted FAT 32 with a Volume Label = "FINDING" ). The memory stick should have 1 single Fat32 partition It must be of very low capacity, of 128 Meg bytes maximum? Because the memory stick must Not have a MBR system. Copy your own experimental program to the empty memory stick as a file. Log off, turn off the computer, turn back on, press a number and your program should be able to run with computer booting and in "Real mode".. Booting-Aids_2_ can do several things which have a definite educational value, because booting lets your own programs run without an operating system until they can become like a small operating system of their own. ...

    cMIPS

    cMIPS - an FPGA ready VHDL model for 5-stage pipeline, MIPS32r2 core

    This project was moved to https://gitlab.c3sl.ufpr.br/roberto/cmips The code here is no longer up to date. The VHDL model mimics the pipeline design described in Patterson & Hennessy's book (Computer Organisation and Design) and is an almost complete implementation of the MIPS32r2 instruction set. The TLB and assorted control registers will be included soon (as of fev 2015). The model was synthesized for an Altera EP4CE30F23. The model uses up 15% of combinational blocks and 5%...

    EXIRION/OS

    Embedded Operating System

    EXIRION/OS is an operating system for embedded computer systems. These operating systems are designed to be compact, efficient at resource usage, and reliable, forsaking many functions that non-embedded computer operating systems provide, and which may not be used by the specialized applications they run. They are frequently also referred to as real-time operating systems, and the term RTOS is often used as a synonym for embedded operating system. ...
