+# fir4tap1016 - 4-Tap Moving Average FIR Filter
+
+## Description
+A fully synchronous, 4-tap moving average filter RTL IP block. This filter acts as a low-pass DSP module, designed to smooth out high-frequency noise in digital signal streams by continuously outputting the mean of the last four acquired samples utilizing an optimized shift-register pipeline.
+
+## Block Diagram
+Refer to the comprehensive project report for detailed schematics and block diagrams.
+
+## Pin Configuration
+* **Inputs (10):** clk (1), rst (1), data_in (8)
+* **Outputs (16):** filter_out (16)
+
+## Author & Contact
+* **Name:** Hanzala Zafar
