The XS1 family of devices features a multi-threaded processor architecture constructed from XCore processors connected by communication links. The architecture is scalable and any number of XCore processors can be connected together.
Applications are developed using a combination of XC, C, and C++. XC provides extensions to C that simplify the control over concurrency, I/O and time. These extensions map directly to XS1 device resources making it easy to write embedded applications that require a blend of control code, DSP, and interfacing.
