+# LAB2 Project Presentation
+
+## Project Description
+
+The LAB2 project consists of the design and implementation of a digital system for image processing and data communication. The system is composed of several functional blocks, each responsible for a specific task in the processing pipeline. The main objectives are:
+
+- Receive and process image data
+- Perform color space conversion (e.g., RGB to grayscale)
+- Apply convolution filters to the image
+- Packetize the processed data for transmission
+- Support loopback and test modes for verification
+
+## Block Diagram
+
+Below is a conceptual block diagram of the LAB2 system:
+
+```mermaid
+flowchart LR
+    IN[PC] -.-> UART[UART]
+    UART -.-> IN
+    UART --> DEPACK[Depack]
+    DEPACK --> C2G[Color to Grayscale Converter]
+    C2G --> BRAM[BRAM Writer]
+    BRAM --> Underflow
+    BRAM -->Overflow
+    BRAM -->Ok
+    BRAM <-.-> CONV[Convolution Filter]
+    BRAM <-.-> CONV
+    CONV --> PACK[Packetizer]
+    PACK --> UART
+```
+
+## Areas for Improvement
+
+- In loopback mode, when sending an empty packet (FFF1), the module temporarily stores H and F and prepends them to the header of the next packet. There is an error in the pack/depack logic.
+- The implementation of the depacketizer is complex, and the precise error has not been identified.
+- The color conversion (C2G) uses a divider by 3, but the approximation method is unclear (it sums half of the power-of-two factor used in the divider—why?). -> Just add comments explainig how it works
+- Convolution is performed with various unconstrained integers.
+- In general, the VHDL code is somewhat complex, although generally correct. Aim to simplify and make the code more readable.

+- JSTK: Non-atomicity in writing to the RGB LED; the rest is well done and clear.
+- Mute: (IF s_axis_tvalid = '1' AND m_axis_tready = '1' THEN) AXIS error; s_axis_tready should be checked. The original would be correct if s_axis_tready was directly connected to m_axis_tready. As written, it waits for ready to assert valid.
+- Volume controller: Waits for ready to assert valid (IF s_axis_tvalid = '1' AND m_axis_tready = '1' THEN).
+- Balance: (IF s_axis_tvalid = '1' AND m_axis_tready = '1' THEN) AXI condition is incorrect; the rest is correct.
