They provide access to ® all signals that are needed for a wide range of I/O connectivity. The signals on the micro-line connectors can be grouped into the following categories: • power supply • DSP- and board specific interfaces, suc

It can also be generated by the FPGA, allowing any clock frequency up to 100 MHz. Compared to the internal fast SRAM of the DSP chip, the on-board SDRAM is significantly slower. Therefore it is strongly recommended to use the internal memory of the DSP whenever it is possible. The internal memory can be use

Software drivers for the temperature sensor are included in the development kits, see [20] for details. Further information can be found in [18]. 2 The temperature sensor is connected to the PLD by a separate I C interface. It does not use the 2 2 I C i

They can be switched on and off by application software to display certain events or states. Examples for software controlled usage of the LED's are: • displaying an error condition by the red LED • checking software activity by toggling one of the L

The timers support two signaling modes and can be clocked by an internal or an external source. Each timer has a separate input pin and an output pin. Using an internal clock, for example, the timer can trigger an external A/D converter to start a conversion, or it
