The Blob Detector IP Core is a high-performance hardware accelerator for detecting and localizing the brightest blob in grayscale images. It computes the blob centroid with subpixel accuracy, making it ideal for precision imaging tasks in real-time systems. The core supports two centroid refinement methods—zero crossing and parabolic peak shift—and offers both streaming and single-frame processing modes.

• Detects and localizes the brightest blob in grayscale images

• Subpixel centroid estimation via zero crossing or parabolic peak shift

• Supports both single-frame and continuous streaming modes

• Flexible kernel configuration (user-defined, up to 127×127)

• High-throughput convolution engine with 1-pixel or 4-pixel per cycle processing

• Image resolution up to 65535×65535 pixels

• Interrupt support for result readiness (X/Y coordinates and extrema value)

• Delivers coordinates in Q16.8 fixed-point format

• AXI-Stream interface for image input

• APB interface for configuration and result access

• Verified on Microchip PolarFire FPGA

• Demo project available for MPF300-VIDEO-KIT-NS

The 2DFIR IP core performs high-efficiency 2D convolution on monochrome images using user-defined kernels of up to 32×32 pixels. Designed for advanced image enhancement, feature extraction, and filtering, this core enables real-time processing of high-resolution images in hardware. It supports multiple operation modes, including configurable kernel switching and simultaneous multi-kernel filtering.
