Industrial-grade core board based on AM5728 dual-core ARM Cortex-A15 + floating-point dual-core DSP C66x processor design

1. Introduction to the core board

Chuanglong SOM-TL5728 is a high-end heterogeneous multi-core SoC industrial-grade core board based on TI Sitara series AM5728 dual-core ARM Cortex-A15 + floating-point dual-core DSP C66x processor design. Gigabit Ethernet, PCIe, USB 3.0, GPMC, SATA, HDMI and other interfaces are led out through industrial-grade high-speed B2B connectors . 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 .

When users use the core board for secondary development, they only need to focus on the upper-level application , which reduces the development difficulty and time cost, and can quickly conduct product plan evaluation and technical pre-research.
