Return to the Moon - AGC in FPGA

Project description:
It's integrate the whole original Apollo Guidance Computer into the one chip design FPGA. Lunar Lander On-board Guidance, Navigation and Control. I choose for this project the Digilent Cmod A7 Artix-7 FPGA platform.

This today to do a kid game already... but up to a certain point. More than 50 years ago, in the early 1960s, Hardware: 2800 ICs, dual three-input NOR gates, 2K magnetic core RAM, 36K core rope ROM In total, software development on the project comparised 1400 person-years of effort, I have 4 month for this work. This is not only a replica, or simulator, but an operational prototype, what is able to drive a fed trajectory of flying data off from an Earth orbit one robotic Lunar Module landing on the surface of the Moon.

48-pin DIP form factor board built around a Xilinx Artix-7 FPGA

from Digilent.com

It can integrate programmable logic design directly into a solderless breadboard circuit.

At just 0.7” by 2.75”

The board also includes a USB-JTAG programming circuit, USB-UART bridge, clock source, Pmod host connector, SRAM, Quad-SPI Flash, and basic I/O devices.

The Cmod A7 is fully compatible with the high-performance Xilinx Vivado® Design Suite.
