As a hot technology, virtual reality has developed in recent years. There are many “cross-domain†enterprises in the field of VR chips, such as MediaTek, Qualcomm, Samsung, etc. Manufacturers.
Rockchip Micro RockchipRockchip Micro Rockchip introduces the new flagship processor chip of RK3399, which can be applied to many fields such as VR, game box and tablet. In the tablet market, a differentiated, high-performance, and highly targeted tablet computer revolutionary from the industry's original chip manufacturers has ushered in.
Rockchip Micro Rockchip RK3399 has a strong upgrade to the overall architecture. The processor CPU uses a dual Cortex-A72 large core + four Cortex-A53 small core, big.LITTLE size core architecture. The GPU uses the Mali-T860 image processor. The CPU has large integer, floating point and memory optimization, and has high performance and low power consumption. The Mali-T860 is the latest generation of high-end graphics processors, with an overall performance improvement of 45% over the T628.
The Rockchip RK3399 processor is used in 2in1, Android business tablet, high-performance tablet terminal products with six product advantages:
1. Integrated dual USB3.0 type-c interface, type-c Display Port audio and video output.
2. MIPI/eDP interface, support 2560&TImes; 1600 display and dual display.
3. Built-in PCI-e interface supports PCI-e-based high-speed Wi-Fi and storage expansion.
4. Support high bandwidth LPDDR4.
5. Dual ISP pixel processing capacity up to 800MPix/s, support for 3D images.
6. Compatible with Android, Linux and other operating systems.
Analysts say that the RK3399 processor solution is designed for commercial tablets and high-end tablets with faster and lower power consumption. Dual USB3.0 type-c, dual ISP, PCI-e interface, support for LPDDR4 memory and many other new features, are ahead of the current mainstream mainstream tablet products.
MediaTek launched the Helio X30 ten-core processor. As its second-generation ten-core processor, the Helio X30 still has a lot of parameters. Although the three-segment architecture is still used, it is two Cortex-A73 cores with a frequency of 2.8GHz and four Cortex-A53 cores with a constant frequency of 2.3G and four Cortex-A35 cores with a clock speed of 2.0GHz. The Cortex-A73 core has the strongest performance, and the four Cortex-A53 performances are second. Although the four Cortex-A35 cores are the weakest of the three cores, their energy consumption ratio is the highest. In addition to changes in the process and architecture, the Helio X30 has also made great improvements on the GPU. Instead of using the ancestral Mail series core, it chose the quad-core imaginaTIon PowerVR 7XTP, knowing that almost every generation of Apple mobile devices will use PowerVR series GPU core.
Full ambitionBased on TSMC's 28nm manufacturing process, Quanzhi H8 is based on 8 ARM Cortex-A7 cores and supports 8 cores and 2.0GHz high-speed operation. It also works with ImaginaTIon's powerful PowerVR SGX544 image processing architecture, with a working frequency of up to 700M. In terms of multimedia, H8 supports multi-format 1080p@60fps video codec, supports H.265/HEVC video processing, and integrates 8M ISP image signal processing architecture to support 8 megapixel camera. In terms of display, H8 supports HDMI 1080p@60fps display, supports HDCP V1.2 protocol, and supports HDMI CEC. In addition, the H8 integrates the new generation of Lixin display technology, and the image display quality is further improved.
The torch core S900VR is a chip developed by the torch core (Zhuhai) Technology Co., Ltd. based on the VR field.
The S900VR is a high-performance, low-power, diversified and highly integrated 64-bit quad-core master chip for the VR all-in-one market. The S900VR master chip uses a 28nm process and integrates a quad-core CortexTM-A53 with a TrustZone security system and a PowerVR G6230 high-performance graphics processor from ImaginaTIon. In terms of video decoding, it supports HEVC (H.265) format ultra-high definition (4K x 2K) video hard decoding, and other mainstream video formats HD decoding support. In terms of image encoding, in addition to supporting 1080P@60fps encoding capability, it also integrates a high-performance image processor (ISP) to achieve high-quality processing of images up to 13M pixels.
Shanghai Yingfang MicroelectronicsIn the Tencent miniStation micro-game machine, after dismantling, it was found that two logos were printed on the main chip: Tencent and INFOTM.
INFOTM is the English name of the company "Shanghai Yingfang Microelectronics", a professional integrated circuit design company specializing in the development of mobile Internet terminal application processor chips. Typical applications are tablets, smartphones, cameras and cameras; it also provides partners with integrated solutions for systems, software and chips.
It seems that this custom chip should be designed and processed by Tencent Entrusted by Infront Microelectronics, and then both parties will have a logo on the chip to form a dual brand.
Basic information and features of this custom chip:
1. The internal use of high-performance 128-bit processor, it is said that unlike the current mainstream 64-bit processor, the execution efficiency is higher in data processing; therefore, ultra-low latency data processing can be realized.
2. Parallel processing of multi-channel multimedia data, including audio, video and interactive data;
3. Adopt advanced image processing and transmission technology; these should be important technologies for achieving ultra-high wireless cross-screen transmission.
4. Special algorithm optimization for VR technology.
It is also not excluded that the success of Infront Microelectronics' customized chips will drive the company to gradually introduce generic products to the sales of VR vendors.
