BERTEN is a private company founded by engineers with aerospace technology experience to provide high-speed electronics and embedded software for complex and demanding environments in defense, avionics, navigation, unmanned vehicles, scientific research and many more. BERTEN specializes in the development of advanced electronics, signal and power supplies, and has a wide range of products including firmware development, software acceleration and FPGA design. Standard products such as the rugged SBC (single board computer) with the latest FPGA and SoC technology can work in harsh environmental conditions.
Processing Gigabit Ethernet data in real-time in programmable logic (PL) is a very time consuming process, with the option of optimizing drivers and interface management to improve this problem. System-on-a-chip (SoC) devices provide hardware resources that allow this type of communication, but lack common software applications that implement this functionality. The company has developed a high-speed API.
GigaX High Speed ​​API:At the end of last month, Berten DSP released a new GigaX API for the Xilinx Zynq SoC, creating a full-duplex communication channel between the GbE port and the Zynq SoC using a SDRAM buffer and an AXI DMA controller IP block. . The detailed architecture can be seen from the chart below:

The software API implements IP filtering and TCP/UDP header management functions to implement hardware acceleration functions of various Ethernet systems, including Ethernet bridges, programmable network nodes, and network offload devices. The relationship between throughput and packet loss rate is detailed in the following performance curves:

Zynq SoC:Zynq Soc is an ARM-based scalable platform developed by Xilinx, integrated single-core or dual-core ARM Cortex-A9, scalable FPGA logic density board, and extensive OS support to match familiar embedded Tools, as well as a rich set of development boards and kits, are the most integrated and low-cost entry-level ARM SoCs in the current FPGA portfolio, as well as software and hardware field upgrades.
The Zynq-7000 SoC integrates a single-core or dual-core ARM Cortex-A9 APU, 1GB DDR3 memory, programmable logic (PL), and a variety of peripheral controllers, so it is perfectly implemented in ARM software and has Functions such as cloud analysis and cloud connectivity are currently used in machine vision, multi-axis motor control, multi-camera driver assistance platforms, Ethernet-based backhaul solutions, monitors and projectors, multifunction printers, video surveillance systems, etc. Very wide.
to sum up:Since the launch of Zynq Soc in many fields, Zynq's products are highly competitive and cost-effective, and the GigaX API launched by Berten DSP has once again improved the interaction between the board and the network. In the meantime we will see more and more excellent products based on Zynq Soc.
Aquarium lights, also known as water plants growing lights, are mainly made of LED lamp beads, also known as LED aquarium lights, LED water plants growing lights, and LED water plants supplement light.
Aquarium lamp is a special kind of lamp, according to the growth law of plants, it must need sunlight, and the aquarium lamp is a lamp that uses the principle of sunlight to replace sunlight to provide the environment for the growth and development of aquatic plants.
