Smartphone firmware can be very sophisticated, and migrating software to new host processors can be costly and time consuming. The development of some of the underlying mobile application processors has not kept pace with market demand for new features such as VoIP calls and GPS. In particular, some processors have only low-speed UARTs, and just one SD (Secure Digital) host controller for peripheral connection.
Faster UART performance is a common request seen by QuickLogic. The standard UART capability integrated into some recent mobile application processors is a major limiting factor, as they tend to conform to the traditional UART role of low data-rate serial communication for applications such as a PC serial port. This is a particular problem for developers who need to support the latest high-speed EDR (enhanced data rate) mode of Bluetooth — a very important function for phones targeting business and high-end users.
