Test for Success Integrated-interface/scaler products are true mixed-signal devices that require 100% high-speed mixed-signal electrical testing to ensure the highest-quality performance. Mixed-signal test solutions for A/D converters are now nearly as complex as the chip design itself.

The CompactRIO hardware platform (see below) is an example of an embedded system that leverages FPGA technology for applications that require high performance and reliability. The system combines an open embedded architecture with small size, extreme ruggedness, and hot-swappable industrial I/O modules. The CompactRIO platform is based on an FPGA directly connected to I/O modules that provide signal conditioning and isolation for sensors and automotive buses. Since the FPGA on CompactRIO is programmed with LabVIEW, any engineer can take advantage of the benefits of FPGAs.

And the amount of time for useful work within a single clock cycle can be rewritten as:

Another complex issue is the ability to lip-sync or decode the audio at the same time as the matching video so that a person's voice is played through the speaker at the same time they move their lips. Each of the two independent streams of data has a timestamp on each packet that indicates the time it was created. Since the video packets take substantially longer to decode, an algorithm runs on the DSP processor to delay the audio packets so they will be decoded at the same instant as the matching video packets. If any packets are lost, the algorithm generates blank packets to fill the spaces. As you might expect, rewind and fast forward operations put considerable stress on this algorithm.

The resultant amplifier is remarkably space efficient: A two-channel, 120W/channel Class D reference design fits on a 1.5″ x 3.125″ PCB, requires no heat sink, and locates all components for the Class D switching stage on the board’s top surface. The design uses a self-oscillating PWM modulator to minimize the component count and a 2nd-order integrator for the error amplifier. The advantage of this modulator over a carrier-based design is that the self-oscillating modulator shifts in-band errors out of band while it provides sufficient correction to deliver good performance from a half-bridge power stage.

A typical state-of-the-art event correlation system is comprised of the following main components (See Figure 2) :

New generation of development boards Today, a new generation of development boards are emerging that dramatically reduce time, cost, and risk involved in delivering an integrated DSL STB. An example of these boards is a development board that incorporates AR7 DSL and DM642 video chips, already present in most integrated STBs to date. The DM642 is based on a DSP core and includes instruction set extensions for accelerating video and imaging applications, providing full software programmability. This enables a user to, for example, roll out an MPEG 2 product and later upgrade to H.264 video codec. The MIPS CPU within the AR7 router on a chip is responsible for managing the DSL link, performing IP routing and transport stream demultiplexing to deliver raw compressed audio/video data to the DSP (See Figure 1) .
