The project is implemented with Xilinx ISE 14.7 but it should be easy to migrate it to Vivado. For Altera platforms, some IP cores must be adapted. Includes Xilinx ISE testbench and wave configuration files.
All the contents were developed for the passive remote sensing group (RSLab) as a part of the Remote Sensing Laboratory, a research line of the CommmSensLab Group at the Signal Theory and Communications Department (TSC) of the Universitat Politècnica de Catalunya (UPC).

|---|---|
| AND_sync.vhd | Ensures a pipelined AND operation of large vectors by nesting smaller ANDs. |
| OR_sync.vhd | Ensures a pipelined OR operation of large vectors by nesting smaller ORs. |
| compare_vectors.vhd | Compares if two vectors are equal. Pipeline is ensured by proper setting the size of the AND_sync entity. |
| detect_change.vhd | Detects a change on a vector. Pipeline is ensured by proper setting the size of the compare_vectors entity. |
| strobe_adapter_fast2slow.vhd | Adapts a strobe line from a fast clock to a slower clock. |
| strobe_adapter_slow2fast.vhd | Adapts a strobe line from a slow clock to a faster clock. |
| priority_encoder.vhd | Finds the MSB of a vector. Pipeline is not ensured if the vector is too large. |
| priority_encoder_nested.vhd | Finds the MSB of a vector. Pipeline is ensured by nesting priority_encoder and by proper setting their size. |
| sync_SIGNALS.vhd | Sync signals with same rate. |
| generic_decoder.vhd | Generic BCD-to-decimal decoder. To be done. |
| generic_decoder_accum.vhd | Generic BCD-to-decimal decoder with accumulation. To be done. |

|---|---|
| max_vector_8.vhd | Finds the maximum between 2 unsigned vectors of 8 bits. Pipeline is ensured. |
| find_MSB_complex_32.vhd | Finds the MSB of a 32 bits complex unsigned signal (i.e. 32 bits I + 32 bits Q). Pipeline is ensured by proper setting the priority_encoder_nested. |
| find_MSB_complex_epoch_32.vhd | Finds the MSB of a 32 bits complex unsigned signal (i.e. 32 bits I + 32 bits Q) with a non-sliding window of "EPOCH" samples. Pipeline is ensured by proper setting the priority_encoder_nested. |
| agc_16_complex.vhd | Continuous AGC of a 16 bits complex signal (i.e. 16 bits I + 16 bits Q). |
| moving_average_FIR_256_8_SIGNED.vhd | Moving average of 256 samples of a 8 bits signed signal. |
