NES On-A-Chip – The Embedded System in VHDL

First of all, did you know what VHDL is? For your information, VHDL is commonly known as a design-entry language for field-programmable gate arrays and application-specific integrated circuits in electronic design automation of digital circuits. VHDL is derived from VHSIC hardware description language, where VHSIC stands for “Very-high-speed-integrated circuit”.

Based on the information, VHDL was originally developed at the US Department of Defense. The main purpose of the mission is to document the behavior of the ASICs that supplier companies were including in equipment. This means, VHDL was developed as an alternative to huge, complex manuals, which were subject to implementation-specific details.

Well, this NES On-A-Chip’s main goal is to implement an older embedded system entirely in VHDL. In this case, you might want to choose the NES, as its complexity and variety of subsystems. The whole idea is to prove that chips can be modeled in VHDL and synthesized on an FPGA. Furthermore, it can be used to replace, either single ICs in old systems or the systems themselves.

You have to prepare the Altera UP3 development board to implement the design. In addition, you must use an Intronix LogicPort USB logic analyzer as well.
