Xilinx Spartan-6 LX and Spartan-6 LXT families [DS160] DSP48A1 DSP block is presented. …
Since, in the structure of the DSP block, a partition multiplier, aggregators and conveyor
registers are present, three DSP48A1 blocks will be needed to implement a PID controller.
The block diagram of the controller implemented with the built-in FPGA devices of the
Spartan 6 DSP block DSP48A1 series is shown in Figure 3. The DSP1 …
