Introduction to Evaluation Board
Chuanglong TL6678-EasyEVM is a high-end multi-core DSP evaluation board based on TI's KeyStone architecture C6000 series TMS320C6678 octa-core C66x fixed-point/floating-point high-performance processor. It consists of a core board and a backplane. The core board has been verified by professional PCB Layout and high and low temperature testing, which is stable and reliable and can meet various industrial application environments .
The evaluation board has rich interface resources , leading to high-speed communication interfaces such as dual Gigabit Ethernet ports, SRIO, PCIe, etc., which is convenient for users to quickly evaluate product solutions and technical pre-research.
