How to make RISC-V Microcomputer using FPGA for programmer

This book is intrduction for programar that how to design microcomputer. It describes from which the explanation of logic gates such as AND and OR, to which the design of a microcomputer that combines CPU and peripheral devices such as VGA screen display circuit with FPGA(Field Programmable Gate Array) board.

An FPGA is an Integrated Circuit that allows users to freely change the logic and wiring of hardware. They can change the configuration of the hardware logic circuit. Therefore, they can freely create from a circuit that simply turns on/off LEDs, to CPU which is one of the most complex logic circuits. Moreover, they can also implement the functions of the microcomputer by putting together the input/output, the CPU etc together.

In this book, we will make microcontroller using the FPGA board, which has the IC chip of the FPGA, VGA, LED, switches, etc. For FPGA design, we use Chisel that is open source hardware construction language. In addition, we use RISC-V (pronounce risk five) that the instruction set specification is open and free for design of the microcomputer. First of all, we create a pipeline RISC-V CPU with only partial instructions from scratch.
After that, we create a microcomputer using Freedom Chip. Freedom Chip is an open source RISC-V implementation.
