The 4K Video Scaler by Zipcores is engineered for studio-quality RGB scaling, optimized specifically for UHD and 4K resolutions. It supports processing of 2 pixels per clock and can achieve an effective pixel clock rate of up to 600 MHz, making it suitable for mid-range FPGAs and SoCs. The scaler provides simple input and output interfaces that are compatible with the AXI4-stream standard, and it operates without the need for a frame buffer or external memory, enhancing its efficiency.
Zipcores' Text Overlay Module enables the insertion of text onto 24-bit RGB video streams. Users can define text characteristics such as font size, transparency, animation, and highlighting. The module supports various interfacing options, including I2C, SPI, or UART, facilitating easy integration with existing systems. It is ideal for broadcast environments where customizable and dynamic text insertion is essential.
The Bayer to RGB Converter takes the raw Bayer pattern data from digital image sensors and interpolates it into full 24-bit RGB resolution. It utilizes an adaptive 5x5 polyphase filter to significantly reduce artifacts such as jagged edges and zipping, making it an essential component in the initial stage of image processing pipelines. This converter is designed for high-quality image outputs, which is crucial for various digital imaging applications.
The GPU Overlay Module accommodates the overlay of anti-aliased 2D graphics and text on 30-bit RGB video streams. This IP core extends the functionality of the Text Overlay Module by adding advanced graphics features, making it suitable for on-screen display applications where professional-grade aesthetics are required. It integrates seamlessly with user graphics systems, enabling vibrant, interactive graphical interfaces.
Zipcores' Digital Video Scaler facilitates both up and down video scaling, allowing independent adjustments for horizontal and vertical dimensions to create any desired aspect ratio or resolution. Utilizing a 5x5 FIR polyphase filter with 16 phases, this scaler ensures studio-grade output quality. Like the 4K Video Scaler, it requires no frame buffer or external memory, which simplifies integration into existing video systems.
The Multi-format Video Deinterlacer by Zipcores is designed to convert interlaced digital video formats like 480i, 576i, and HD1080i into high-resolution progressive outputs. It eliminates the typical combing and tearing artifacts associated with deinterlacing, ensuring sharp video quality. The proprietary algorithm used in this module allows for cleaner edges and a reduction in softening effects, making it ideal for professional digital video processing applications.
The N-channel Multiplexed FIR Filter is an innovative design that merges multiple input channels into a single FIR filter architecture. It uses fewer resources compared to implementing multiple FIR filters in parallel, making it highly cost-effective for processing dual-channel inputs or complex-valued I/Q data. The filter's architecture is fully configurable, making it adaptable to varying application needs.
The 16-bit Binary-PSK Demodulator is designed for low-cost radio communication applications. Not only does it provide excellent noise immunity and dynamic range, but it also ensures automatic carrier lock without requiring complex PLL setups or tuning. Ideal for short-distance radio links, this demodulator supports symbol rates up to 10 Mbps, making it suitable for various digital communication systems.
Designed to improve digital video quality by removing high-frequency artifacts, the Digital Video Anti-aliasing Filter employs a 3x3 low-pass filter to smooth out image pixels. This filter is adept at eliminating issues like jagged edges, stepped lines, and Moiré patterns, particularly useful in conjunction with image sensors or prior to video downscaling processes. By enhancing the visual quality of the video signal, this anti-aliasing filter is invaluable for high-definition video processing scenarios.
The Zipcores Complex Digital Down Converter is designed for precise conversion of IF signals to baseband, suited for subsequent digital processing. It includes a fully configurable decimation filter stage and a precision digital oscillator, providing superior precision for IQ demodulation. This IP core demonstrates exceptional performance and flexibility, making it an integral part of advanced signal processing workflows.
Zipcores' Digital Video Anti-aliasing Filter plays a critical role in eliminating high-frequency artifacts from digital video streams. By implementing a 3x3 low-pass filter, it smooths image pixels to remove unwanted elements like jagged edges and patterns. This filtering process is particularly effective when used with image sensors or prior to downscaling in video applications, optimizing the visual output for clearer and cleaner display results.
