Imagination Technologies, Inc., has announced the first members of its PowerVR Series4 video core. This article refers to the address: http:// The PowerVR Series4 D4500MP video decoder and E4500MP video encoder are based on the highly successful PowerVR VXD and VXE Series3 multi-standard video codec technology. These multi-channel architecture video silicon semiconductor intellectual property (IP) offers enhancements for modern application design, such as unprecedented color accuracy for wireless display and video capture, and high definition (HD) and ultra high definition (Ultra-HD) displays. With industry-leading performance, these video processing cores maintain a small footprint and ultra-low power consumption, making them ideal for consumer electronics applications. These cores offer full scalability from single to quad, ensuring 1080P performance and low power consumption in a compact area, or industry-leading 4Kx2K performance. “With the ability to process more than one billion colors in full resolution, the enhanced color processing capabilities of the PowerVR D4500MP and E4500MP ensure significant performance improvements for today's demanding video applications, with crisper and more precise video content available for applications such as Contemporary applications such as wireless display and high-quality video capture.†Toony King Smith, vice president of marketing at Imagination, said: “As the supply of OLED displays and 10bit displays that offer a wider color gamut grows, consumers demand experience more than ever. Higher color fidelity. In addition to the ultra-real-time HD video processing performance, these cores are perfect for today's widest range of display applications, as well as for large wall displays and giant stitching screens. Such future ultra-high definition (Ultra-HD) 4Kx2K applications provide more than enough performance guarantees." Full resolution, true-to-life color processing, supporting over one billion colors The PowerVR D4500MP and E4500MP support enhanced color depth, delivering up to 10-bit color accuracy for over one billion colors, while today's traditional 8-bit systems offer only 16 million colors. The increase in color depth support allows the SoC to maintain high-precision internal processing from the video source to the display output for true, true-to-life color reproduction. Enhancements in color performance provide the color fidelity required for the latest generation of 10-bit and OLED displays to ensure maximum performance. The use of 10 bits also helps to significantly reduce the color banding in traditional 8-bit systems. To further enhance the color rendering capabilities available, the video processor core has increased color resolution to 4:4:4 (or 4:2:2) to provide full resolution data for all video unit components. This makes the conversion between YCbCr and RGB easier and more precise by eliminating the need for interpolation, making it perfect for wireless display subsystems. Repeated conversions between traditional color formats (and resolutions) can result in loss of detail and blurring due to interpolation errors, while the use of 4:4:4 guarantees that such errors are eliminated. The enhanced resolution and fidelity performance of this family of cores enables applications such as camcorders, digital cameras, SLR cameras and mobile phones to maximize the performance of image sensors that typically provide at least 10-bit color depth, enabling them to deliver unprecedented levels of performance. Professional-grade image quality provides manufacturers with product differentiation and added value to consumers. Encoding and decoding performance for future applications The PowerVR D4500MP and E4500MP increase the decoding and encoding performance of full HD 1080P video applications, respectively, ensuring high-definition quality for ultra-high-definition quality, multi-stream HD channel browsing, high-speed continuous fine slow motion for sporting events and other special content. stand by. These new cores also deliver industry-leading performance for ultra-high-resolution 4Kx2K video, which is the core technology for future video applications, delivering four times the visual information capacity of traditional high-definition televisions and the "information wall" flat display. Apps that combine TV with apps, social media, and channel browsing. The inner core of the IP core The PowerVR D4500MP supports all major video standards including H.264 HP, H.264 MP, H.264 BP, H.264 MVC, VC-1, VP8/WebM, H.263, RMVB (Real Video), MPEG- 2. MPEG-4, AVS, VP6 and JPEG. The PowerVR video core remains the industry's record holder for low power consumption, which can decode H.264HP 1080P30 video with less than 15 milliwatts (40LP process). The PowerVR D4500MP multi-standard, multi-stream video decoder IP core uses a multi-core architecture to enable performance for high-resolution or high frame rate applications with ultra-low power consumption when using mainstream silicon semiconductor process technology. Requirements are configured until the full H.264 level 5.2 rating is supported. This unprecedented performance ensures that 4K resolution content is decoded and output with H.264 L5.2 4Kx2K@60fps. By allowing code streams of any format up to H.264 HP to be decoded at ultra-real-time speed, the PowerVR D4500MP ensures support for an ever-increasing number of applications that greatly enhance the user experience, including 1920x1080@120fps high-speed photography slow motion playback decoding, Trick play mode and video editing application. The PowerVR E4500MP is a multi-standard, multi-stream video encoder that supports all major high definition video and still image standards. In addition, the E4500MP supports up to 4Kx2K@30fps resolution encoding. The E4500MP's video source scaling component reduces the stream size of the video source, which is an important application feature for new applications such as adaptive streaming, simulcast low resolution and high resolution video. The E4500MP core also supports H.264 lossless mode, which is a basic requirement for applications such as highest fidelity video transmission.
Rotary ploughing Cultivator Machine:
This ploughing cultivator is centered on a
rotating column and surrounded by ploughing knives. The land ploughed by our
machines is very loose, the soil has been improved, fertilizer and soil
conservation. Through cultivated land, the surface soil layer of a year is
turned to the lower layer, so soil maturation is accelerated, which is
conducive to promoting the journey of soil aggregate structure, thickening the
living soil layer, deepening the cultivation layer, and increasing the living
soil layer.
