+
+== 1) Functional Description ==
+
+The mapping operation consists in modulating the inputs bits into symbols (complex signals). In our system, the used mapping is a QPSK (Quadrature Phase-Shift Keying) modulation. This means each symbol is coded by two bits.
+The architecture of the mapping component is presented in the figure 1. It is composed of a mapping core and a MWMR wrapper. The wrapper is used to interface the core and the MWMR controller avalaible here [wiki:Component/VciMwmrController VciMwmrController].

+
+== 2) Component definition & usage ==
+
+=== Component definition ===
+
+  * source:trunk/soclib/soclib/module/ofdm_chain_components/mapping/caba/metadata/mapping.sd
+
+=== Usage ===
+
+Mapping has a ''fifo_depth'' parameter, which defines the fifo depth for the input.
+For example with a FIFO depth equal to 16 :
+        Uses('Mapping', fifo_depth = 16);
+
+== 3) CABA Implementation ==
+ 
+=== CABA sources ===
+
+ * interface : source:trunk/soclib/soclib/module/ofdm_chain_components/mapping/caba/source/include/mapping.h
+ * implementation : source:trunk/soclib/soclib/module/ofdm_chain_components/mapping/caba/source/src/mapping.cpp
+
+  
+=== CABA Constructor parameters ===
+
+{{{
+Mapping(
+     sc_module_name name,                     // Instance name
+     int ncycles)  // Number of computation cycles
+}}}
+
+=== CABA Ports ===
+
+ * sc_in<bool> '''p_resetn''' : hardware reset
+ * sc_in<bool> '''p_clk''' :  clock
+ * soclib::caba::FifoOutput<uint32_t> '''p_to_ctrl''' : interface from the mapping to the MWMR controller
+ * soclib::caba::FifoInput<uint32_t> '''p_from_ctrl''' : interface from the MWMR controller to the mapping
+
+== 4)  TLM-T Implementation ==
+
+The TLM-T implementation is not yet available.
