PNG-E: PNG Lossless Compression Encoder
このオファーについて
The PNG-E core implements a lossless image compression engine compliant with the Portable Network Graphics (PNG) file format specified in the ISO/IEC 15948 and RFC 2083 standards. The encoder core can compress greyscale or color (RGB) images, with 8 and 16 bits per color, with or without alpha transparency, and produces complete PNG files. It exhibits excellent compression efficiency thanks to its ability to automatically and dynamically choose the optimal prediction filter per line. It supports all four prediction filters, LZ77 with a configurable history window, and static huffman tables, and computes CRC and Adler32 checksums as provisioned by the standard. The core does not currently support the interlaced mode, dynamic huffman tables, and images with less than 8 bits per color, but these can be added on request. The easy-to-use PNG-E core interfaces to the system via standardized AMBA® interfaces: it accepts images and outputs compressed data via AXI4-Stream interfaces and provides access to its control and status registers via a 32-bit APB interface. After its registers are programmed with the image dimensions and color format, the core can encode an arbitrary number of images without requiring any assistance or action from the system. The core provides one interrupt signal per direction to facilitate integration with a DMA engine. These interrupts are asserted when the input or output FIFO occupancy reaches a run-time programmable threshold.

Founded in 1993, CAST continues to thrive as the longest-running — and most experienced — independent IP supplier. Our mission has been to provide proven, low-risk IP cores, under simple and flexible licensing terms, coupled with outstanding support. The years of work we have done to perfect IP reuse, improve IP quality standards, and refine sales and business practices yield a product line and a partner network that offer you a better IP experience, today and in the future. Proven, Low-Risk IP: Our goal is to maximize IP benefits for our customers by delivering high-quality, easy-to-use, cost-effective solutions to real system development challenges. CAST quality standards are high, and all our IP undergoes rigorous verification and testing before it gets to you. We use industry-standard verification methodologies, develop and test prototypes, participate in industry collaboration plugfests, and more to ensure proper functioning and smooth integration. Our practices have been extensively tested and proven, as we have helped thousands of customers ship billions of units in hundreds of application areas. Simple, Flexible Licensing: We help you get to work quickly, with fine-tuned project options and licensing terms that ensure smooth legal sign-off. Most CAST IP is available royalty-free, and is extremely cost-effective. Outstanding Support: CAST IP comes with some of the best customer support in the industry. Our goal is to help make you successful, not just sell you IP, and we have the experience and resources to make that happen.
