+The XMC4500 integrates a state-of-the-art processor at its core as well as a broad range of
+highly configurable and powerful peripheral hardware units. This renders this micro-controller to
+be fairly complex for a novice programmer and it took a considerable amount of time to become
+familiar with just a sub-set of the possibilities this controller offers. Therefore the following sub
+sections are going to provide a short overview and introduction into some selected features of
+the micro-controller which are, alongside others, used by the developed firmware.
+
+== ARM Cortex-M4F core
+
+This micro-controller integrates an ARM [1] Cortex-M4F 32bit processor [2] that can be clocked
+to up to 120MHz and implements the ARMv7-M architecture [3]. It is an extended derivative
+of the Cortex-M4 which utilizes an additional IEEE754-compliant [4] single-precision hardware
+floating-point unit (FPU) therefore the "F" post-fix. A conceptual block diagram of this processors
+core is shown in figure 1.

+Its instruction set includes special single instruction multiple data (SIMD), single cycle
+multiply-and-accumulate, saturating arithmetic and hardware division instructions. These features
+provide high computational efficiency and resemble many of the distinct features of dedicated
+digital signal processors (DSP). That is why this group of instructions is often recalled
+in literature as a DSP instruction set. If appropriate algorithms have been implemented these
+instructions are able to increase the computational performance of the processor for certain
+applications significantly. As the processor core needs additional hardware to actually provide
+any useful output the following sub-sections will explain the functionality of selected built-in
+components of the Cortex-M4 core.
