zeST - An implementation of an Atari ST in VHDL
Copyright (c) 2019-2022 by François Galea (fgalea à free.fr)
This is a complete implementation of an Atari ST in VHDL, which targets cheap Xilinx Zynq-7000-based prototyping boards.
Its main features are:
- Cycle accuracy, whenever possible (and necessary)
- HDMI for video and audio output
- USB for keyboard, mouse input (planned: joysticks, mass storage, MIDI...).
External hardware cores zeST is based on:
- Jorge Cwik's fx68k processor core, a cycle-accurate 68000 processor implementation
- Tsuyoshi Hasegawa's HD63701 compatible processor core, used as the keyboard processor
- John Kent's 6850 compatible ACIA core
All other components have been redesigned from scratch.
