【产品简介】

The N3292x includes H.264 codec, MJPEG codec, AAC accelerator and the sound processor and is specially designed for accelerating video/audio streaming performance in the cloud multimedia stream application. H.264 codec and MJPEG codec have a very broad application range that covers all forms of recording, compression and distribution of video content. AAC accelerator can dramatically reduce the amount of data needed to represent high-quality digital audio and the sound processor can improve sound quality; both of them are mainly used for corresponding audio stream. The embedded video codec engines and audio compression/decompression accelerator enhance the application performance to save power consumption while off-loading the CPU.

The N3292x is built on the ARM926EJ-S CPU core and is integrated with video codec (H.264), Ethernet MAC, JPEG codec, CMOS sensor interface, 32-channel SPU (Sound Processing Unit), ADC, DAC and TV encoder for saving the BOM cost in various kinds of application needs. The combination of ARM926 @ 240MHz, DDR2, H.264 codec, AAC accelerator, SDIO host controller and USB2.0 HS Host/Device makes the N3292x be the best choice for video/audio streaming devices.

The N3292x could also be ported under Linux OS to leverage the driver availability of emerging functionalities such as Wi-Fi, browser, etc. On the other hand, the open source code environment provides the product development more flexibility and Nuvoton’s continuous optimizations in Linux provide customers with a cost-effective video/audio streaming solution. Moreover, the 3rd parties USB and SDIO Wi-Fi modules are introduced to best utilize Wi-Fi streaming application devices such as smartphones, tablets, notebooks, smart TV, etc. Maximum resolutions for N3292x are D1 (720x480) @ TV output and 1024x768 @ TFT LCD panel. With the increasing popularity of video streaming resolutions, H.264 is the best fit for limited bandwidth application that requires smaller data rate for high-resolution video. The N3292x is well designed in terms of cost/performance for the video/audio streaming market where Wi-Fi, Ethernet or proprietary RF is extensively used. For 2.4GHz proprietary applications, the hardware CRC generator and checking engines will off-load CPU loading to save the power consumption. Moreover, the hardware channel coding engines including scrambler, inter-leaver, Reed-Solomon outer codec and convolutional inner codec engines are used for more reliable wireless video/audio data streaming in the crowd 2.4GHz ISM band environment.

To reduce system complexity while cutting the BOM cost, the N3292x also comes with a 128-pin MCP (Multi-Chip Package) in LQFP. The 32Mbx16 or 16Mbx16 DDR2 is stacked inside the MCP to ensure higher performance and to minimize the system design efforts, such as EMI, noise coupling. Total BOM cost could be cut by employing 2-layer PCB along with the elimination of damping resistors, EMI prevention components and less board space.
