Low-Cost Unified Pixel Converter from the MIPI DSI Packets into Arbitrary Pixel Sizes
Round 1
Reviewer 1 Report
This manuscript presents a low-cost unified pixel converter, bringing inspiring ideas to solve quite challenging problems. The effectiveness compared to the baseline design in terms of power consumption, etc. was verified through FPGA and synthesis in Samsung 65nm standard cell library. While the manuscript is well organized, I also have many concerns about the technical details noted in this review.
- Page 3, Figures 1 and 2. The units bytes and bits are often mixed in the figures.
- Page 3, Line 98. Section 2.1 only describes the types of packets, so how does a host makes one transaction by mixing short and long packets? It is recommended to state the specific details.
- Page 5, Line 150. For the integrity of your manuscript, it is recommended to add references to the most oversized pixel alignment design.
- Page 5, Line 153. Please explain your purpose and support in designing a unified pixel converter as distinct from the baseline design by dividing it into bases and a remainder?
- Page 6, Line 158. Does this logic still hold for larger pixels, not just 15-byte pixels? Does your proposed unified pixel converter still have the corresponding advantages at this point? please confirm it.
- Page 6, Line 176. Align the 3 MSBs of the output pixel buffer with the cur_ibuf buffer for the remainder and the rest of the output pixel buffer with the prev_ibuf buffer for one and more bases. For this simplified treatment, it is recommended to cite relevant papers to support and further elucidate the rationale, for the integrity of your manuscript.
- Page 8, Line 221. There may be some area overhead when using a base-pixel selector that aligns pixels from the least significant byte, please explain in detail and give the possible solutions.
- Page 9, Synthesis Result. It is suggested that the formula for Reduction be explained in the discussion of the results, and that additional test patterns be added for analysis.
- Page 10, Conclusion. Please comment on whether this unified pixel converter can be extended to include scenarios with other conditions. Are there any other challenges to consider in future research?

Reviewer 3 Report
Article "Low-Cost Unified Pixel Converter from the MIPI DSI Packets into Arbitrary Pixel Sizes" is in subject of MDPI journal Electronics.
Based on elaborated idea was proposed low cost procedure which was verified. The achieved reduction was 25.7% in the area and 38.6% in power consumption compared to the traditional solution.
Article is revelant to publication
