This is the first course on Udemy that teach you about AXI4 bus protocol. If you have a passion about System-on-Chip (SoC), Hardware/Software Co-design, or maybe have a dream to get a job at SoC design company, then this is the first skill that you must have, because most of the SoC toady use AXI.
Advanced eXtensible Interface (AXI) is an industry-standard, system bus for the connection between CPU and peripheral in System-on-Chip design. Today AXI version 4 (AXI4) is used in many SoC that use ARM Cortex-A processors, such as Qualcomm Snapdragon, Samsung Exynos, Broadcom (used on Raspberry Pi), and many more.
ZYNQ is actually a SoC, not just a FPGA, because ZYNQ consists of hard processor system (ARM Cortex-A9) and programmable logic (Xilinx 7-series FPGA, equivalent to Artix-7 FPGA). The ZYNQ device enables the implementation of custom logic such as hardware accelerator in combination with software that runs on the ARM Cortex-A9. ZYNQ can also run Linux OS, which makes this device like the popular Raspberry Pi, but with FPGA inside.
