Zynq SOC Ramp UP.

SOC design leverages Zynq Programmable System (PS) peripherals such as Ethernet/DDR/USB//SPI/I2C generic interfaces.
By using the ARM AMBA AXI<https://en.wikipedia.org/wiki/Advanced_Microcontroller_Bus_Architecture> interface, tasks can be offloaded to the Programmable Logic (PL) that require extensive processing power.

A few examples.
Bitcoin Miner: PS processes Ethernet and DDR buffering, PL performs the SHA256 hash.

Video compression: PS processes Ethernet, PL performs H.264 compression.

However before jumping to the full blown designs, small milestone designs need to be considered.

Some milestone design ideas.

l Template Designs: Hello World, IwIP Echo Server, Memory Tests

l Board Interfaces: LED/Toggle/QSPI/UART/TF/USB/DDR3/Ethernet/HDMI

l PS-PL Access: Fibonacci Number calculation using PL

In order to get started, hardware infrastructure and knowledge ramp up is required.

First is the hardware infrastructure.

I picked up the MYIR Z-turn board because of the price performance.
It includes the Zynq XC7Z020 with larger PL resources for about $120.

Next is the knowledge ramp up. Unfortunately the MYIR documentation and sample designs is rather lacking to say the least.
I am have tried to accumulate a list of training materials to learn more about SOC design to ramped up.
