The AMD Zynq 7000 SoCs family combines an ARM processing system
with programmable hardware logic on a single chip. [

Architecture

• Processing System (PS): Houses a
  single-core or dual-core Arm Cortex-A9 processor. It runs software
  applications and handles system management. 


• Programmable Logic (PL): Uses
  28-nanometer FPGA fabric based on Artix-7 or Kintex-7 architecture. It
  handles custom hardware acceleration and high-speed I/O.
