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
