Description

summary:

Som-am572x is a small and powerful core board, which is based on Ti Sitara am572x series high performance chip design, through multi-core heterogeneous processing scheme, programmable multimedia processing and ultra high speed data communication interface.

Som-am572x core board can lead out the main resource signals of the chip, realize FPGA communication through GPMC bus interface, and support efficient high-speed data acquisition and processing. Due to its flexible interface and powerful performance, som-am572x core board is widely used in industrial automation control, human-machine interface (HMI), machine vision processing, intelligent transportation, VR / AR and other high-performance applications.

We have designed a mature baseboard bb-am5728 for som-am572x, which can be firmly combined through four 2 * 40pin board to board connectors. The baseboard supports commercial and industrial environmental applications, and has completed a series of certification. Once the debugging is completed, it can be directly put into use, which greatly shortens the development time and reduces the R & D cost for enterprises.

EM-TF-SOM-AM5728

EM-TF-SOM-AM5728 is a powerful system-on-module based on TI’s Sitara AM5728 high performance processor,which aims to meet the intensive processing requirements of modern embedded products. Am572x device can achieve high processing performance through its flexible fully integrated hybrid processor solution. In addition, these devices not only have programmable video processing function, but also integrate highly integrated peripheral set. Each am572x device has encryption acceleration function. Dual core arm? Cortex – A15 RISC CPU ; The extension and two Ti c66x VLIW floating-point DSP cores and vision acceleration PAC (with 4 Eve) provide programmability. With arm, developers can separate control functions from other algorithms programmed on DSP and coprocessor, thus reducing the complexity of system software. In addition, Ti provides a set of development tools for arm and c66x DSP, including C language compiler, DSP assembly optimizer to simplify programming and scheduling, debugging interface to view the execution of source code, etc.
