From few years ago, when i was new in space technology program, our instructors gave us a report.

In this report we must develop a Tic-Tac-Toe using ASM Simulator, and this simulator we must develop it too.

Our instructors helped us a little in how we can develop a simple ASM Simulator, and left us to continue developing the game and ASM simulator and they made it worst when they asked it to be Over Network.

My Team consist of 2 people (Me and Islam My Friend), and the report deadline was 2 weeks.

After we studied the topic and the implementation with HLL (High Level Languages), we started to implement it with our custom ASM we defined in the simulator.

The game in first was a console app, but after while before we deliver it we decided to implement UI on it and we used the GTK++ to develop the simple interface.

In this article i will share the source code of the game + simulator under console and with the network support.

Virtual Serial Communication

The Universal Asynchronous Receiver/Transmitter (UART) controller is the key component of the serial communications subsystem of a computer. The UART takes bytes of data and transmits the individual bits in a sequential fashion. At the destination, a second UART re-assembles the bits into complete bytes. Serial transmission is commonly used with modems and for non-networked communication between computers, terminals and other devices. There are two primary forms of serial transmission: Synchronous and Asynchronous. Depending on the modes that are supported by the hardware, the name of the communication sub-system will usually include a A if it supports Asynchronous communications, and a S if it supports Synchronous communications. Some common acronyms are:

  • UART: Universal Asynchronous Receiver/Transmitter
  • USART: Universal Synchronous-Asynchronous Receiver/Transmitter

In This Post we will talk about Virtual Serial Communication and how to emulate serial port to use in you application or simulation.

In my collage, me and my team (AIExtreme) was asked to develop risc processor 32-bit pipelined with assembler. In this post i will demonstrate the latest work in the processor and show the project development phases and status.

Processor Features:

  1. Processor Support 48 Instruction up to 256 Instruction
  2. Processor Interface with 2 Memories [16bit Address, 16bit Data] Interleaved
  3. Interface with LCD Terminal using Instructions
  4. Processor have it’s Assembler
