Nexperia Home 8550

Software Development Kit

The Nexperia™ Home 8550 software development kit (NH-8550 SDK) is

a flexible platform for creating software applications for the Nexperia

PNX8550 home entertainment engine. This complete, assembled kit gives

ISVs and other third-party software companies everything they need to

develop,port, test, and demonstrate applications and libraries forTV, set-top,

digital entertainment hub, and home media server products. It is available

through the Nexperia Home Partner Program.

PNX8550 home entertainment engine

The PNX8550 is a highly integrated media processor capable of supporting

advanced analog and digital TV, multimedia, control, and connectivity features.

On a single chip, it handles conditional access, MPEG-2 transport stream

demux, video decoding, high-quality video enhancements, audio decoding

and mixing, graphics generation, image composition, and display. Powerful

MIPS32 andTriMedia processor cores work together with on-chip units to

efficiently handle control, communications and media processing functions in

hardware and software. The MIPS32 PR4450 CPU controls and balances all

on-chip functions; two TriMedia TM3260 CPUs handle real-time media

tasks, many advanced video enhancements, and all audio operations.

Streamlined application development

In the NH-8550 SDK’s development workflow, software is written on a

host system (such as a PC) then downloaded to SDK reference hardware

through an EJTAG connection. Peripheral interfaces and devices are also

accessible for programming and debugging through the EJTAG interface.

Control and user interface applications for the MIPS core are developed

using OS and connectivity APIs.

Development of streaming media applications for the PNX8550 is simplified

through the Nexperia Home API (NHAPI). The NHAPI is implemented

through a high-performance streaming A/V software layer that abstracts the

This complete, assembled reference platform gives

ISVs and other Nexperia Home Partners everything

they need to create software applications and libraries

for TVs, set-top boxes, digital entertainment hubs, and

home media server products based on the Nexperia

PNX8550 home entertainment engine.

programming interface to the task level through 'use cases.' Use cases

automatically handle both the streaming media processing tasks and all

associated setup steps such as task prioritization, memory allocation,

buffer management,A/V synchronization, etc.The NH-8550 SDK supports

the single-window video and dual-window video use cases.

Standalone (no host) demo mode

The NH-8550 SDK also supports a demo mode that does not require

connection to a host system. In this mode, a preloaded demo executes

on power up, allowing user interaction through the remote control. It

outputs video through DVI or CVBS connections for display. In demo

mode, all peripherals can be controlled and simple control commands

can be given for programming and debugging purposes.

SDK content

The complete NH-8550-SDK includes reference hardware, development

tools, system software, operating systems, A/V streaming software, a

demo/sample application, development tools, and documentation. As

delivered, the it includes software to handle basic analog signal path

functions for multiple audio and video streams.

Reference hardware

Housed in a closed chassis with a power supply, the reference hardware

is preconfigured for system development.The cover can be easily

removed for debugging or configuration. Six push buttons on the front

panel can be programmed through application software to perform sim-

ple control functions. A programmable Philips iPronto

®

remote control

and cables (power, audio, video, and data) are included.

The reference backplane allows connection of a variety of input sources

such as composite video, S-Video, component video, and direct digital

data streams. It outputs to display devices such as a CRT TV, plasma

screen, LCD display, or projector through analog (CVBS) or digital (DVI)

connections.The SDK also includes standard connectivity and control

interfaces such as RS-232 (UART), USB, infrared (remote control), and

GPIO and can be extended with additional modules and PCI cards.

Software, development tools, operating systems

The NH-8550 SDK includes system software, software development

tools, the streaming A/V software layer (NHAPI), operating systems, and

related software documentation. For the MIPS processor, the SDK
