The SmartFusion cSoC integrates FPGA technology with a hardened ARM Cortex-M3 processor and programmable analogue blocks. The OpenGL SC application programming interface (API) runs on SmartFusion’s integrated ARM processor, enabling developers to create graphical user interfaces (GUIs) for standard or customised LCD displays.
The LCD display reference design is architecturally partitioned, with the computationally intensive portion of a customized display controller implemented within the SmartFusion flash-based FPGA fabric. This structure allows product engineers to harness the processing power of the ARM Cortex-M3 for key system layer control task management and algorithm execution tasks. This includes supporting human machine interface (HMI) functionality and various communication protocols that are typically required in industrial and medical applications.
The LCD display reference design also features: a fully customisable LCD controller with the ability to drive different display panels regardless of interface, resolution or manufacturer; an LCD controller supporting timing generation, colour space conversion and alpha blending; an LCD backlight control; and hardware acceleration using FPGA fabric, providing tight integration of processor system and programmable logic.
Microsemi’s LCD display portfolio also includes a new non-dissipative LED backlight driver for LCD TV applications. The recently introduced LX27901 is the first device of its type to provide LED driving capabilities in televisions based on the LCD Integrated Power Supply (LIPS) architecture.
