N3292X Datasheet, PDF (1/8 Pages) List of Unclassifed Manufacturers – ARM926EJ-S 32-bit RISC CPU with 8KB I-Cache & 8KB D-Cache

GENERAL DESCRIPTION
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.
