The world's first automotive multimedia solution integrated with OpenVG accelerator
As a leader in automotive semiconductors, Freescale and Khronos Group have launched an automotive multimedia embedded microprocessor i.MX35 integrated with OpenVG hardware accelerator, becoming the world ’s first automotive multimedia microprocessor integrated with OpenVG hardware accelerator, i.MX35 The outstanding multimedia performance pushes vehicle multimedia to a new height, confirming Freescale's unshakable leading position in the automotive electronics industry.
Low-cost full-features have become the current development trend of in-vehicle multimedia. Automobiles have become an indispensable "entertainment space on wheels" for modern consumers. More and more functions are required for multimedia. Car information, entertainment, and control The demand for integration has become more and more prominent. High integration and low cost will be the focus of automotive multimedia solution providers. And the proportion of this market in the field of automotive electronics is expanding year by year.
Freescale i.MX35 (through AEC-Q100 level 3 automotive certification) is based on the ARM1136JF-S core, clocked at up to 532MHz, has an enhanced multi-level cache system, integrated vector graphics hardware accelerator (OpenVG) independent image processing unit (IPU), Vector floating point arithmetic coprocessor (VFP) and RISC-based DMA controller.
OpenVG is a 2D vector graphics acceleration standard proposed by the Khronos Group, which can provide smooth and delicate 2D / 2.5D picture effects, and obtain better human-machine interface (HMI) display and flexible text font display effects. i.MX35 accelerates OpenVG hardware to achieve smooth interactive performance at extremely low processor power levels. The more direct application is a natural acceleration of Adobe Flash, allowing engineers to design user interfaces directly in Flash without the need for manual C programming. The OpenVG hardware acceleration module also greatly improves the display performance of the GPS navigation system: smooth and smooth map route display effect (excellent anti-aliasing ability) and font display that can be enlarged and reduced according to perspective.
The integration of vector floating-point arithmetic coprocessor (FPU) can easily realize voice control, achieve safe driving, and greatly improve the ability of GPS navigation equipment to analyze and calculate routes.
The MediaLB (Media Local Bus) integrated specifically for automotive applications has strengthened support for the MOST network. As long as it is connected to the MOST INIC, it can be connected to the MOST (Media OrieSystem Transport) multimedia directional system transmission network, which can easily control car audio. Information entertainment equipment such as devices, car TVs, global positioning systems, and car phones. Realize cost-effective and rich and powerful car infotainment system.
The full support of the audio system is another feature of i.MX35: Not only can MediaLB be connected to the MOST network to control the audio equipment, but also through the enhanced serial audio interface (ESAI (Enhanced Serial Audio Interface)) defined by the chip. Channel (5.1 channel) audio output or multi-speaker output. Support S / PDIF digital audio interface. On this basis, flexible playback of multiple audio formats can be achieved.
At the same time i.MX35 has excellent connection performance: supports 2 CAN bus interfaces, 2 USB (OTG / Host) on-chip integrated USB PHy layer, MMC / SD / SDIO port, FEC Ethernet interface and 3 UART interfaces
In terms of memory, i.MX35 has a wide range of options: support for DDR2 and MLC NAND Flash minimizes system cost, and also adds support for Nor Flash with strong stability and fast reading speed, so that customers can get Higher flexibility in product design. The auto software platform AUTO 4.0 released by Microsoft earlier is a reference design that uses the Freescale i.MX35 processor. The system block diagram:
As a Freescale Alliance Member, Shanghai Chenhan Electronics has been focusing on the research and development of Freescale i.MX series products. With the official launch of i.MX35, Chenhan Electronics has also launched the i.MX35 MDK development kit, i.MX35 MDK has maintained Chenhan Electronics' consistent product-level development board design ideas take product development as the starting point for design, and help customers maximize the speed of products to the market.
i.MX35 MDK adopts a flexible core board and motherboard design framework, fully taking into account the domestic mainstream manufacturing process, CPU core board and motherboard are designed with 6-layer and 4-layer PCB boards, reducing the design difficulty and process cost to lowest. On the basis of fully supporting all the interfaces of i.MX35, some necessary interfaces have been added. For example, the three UART interfaces defined by MX35 have been expanded and added by two on the development board to meet the requirements of automotive production.
Product multi-functional design requirements. In addition, MDK development board also provides GPS module interface, Wi-Fi & BlueTooth module interface and CMMB module interface, etc. can realize DVD playback, rear view, GPS navigation, DTV digital TV, Wi-Fi & BT wireless transmission, FM FM radio, Almost all automotive multimedia functions such as MP3 / MP4 / MP5 audio and video playback, voice control, automotive intelligent control, etc., maximize the customer's flexibility in product design.
