Digital signal processor

It's called inertial navigation system or INS.

So what an INS is, is basically it's a-- it's your IMU, which is an accelerometer and a gyroscope, plus a little bit of, you know, um, um, uh, extra compute in the form of like a DSP processor and a microcontroller that processes the signals from the gyroscope and the accelerometers and, uh, essentially does a little bit of, um, um, dead reckoning for you and gives you like trajectories or positions and velocity.

So it kind of integrates the outputs of these, these two sensors.

Uh, so that combined thing is called INS or, uh, um, um, inertial navigation systems.

You can integrate once to get velocity, integrate again to get position.

So essentially, uh, what this step does for you, transforming, uh, which uses the gyroscope input, right, or the integrated gyroscope input to apply that transformation, that is the algorithmic equivalent of what a stable INS does for you mechanically, right? So the stable, uh, uh, um, INS just mechanically moves the thing to align it.

In the strap-down, you apply rotation in math or in DSP or in algorithms to do the alignment.

So the end effect is the same.

Allen's investment of $15 million gave him a less than 20% share.

A former modern manufacturer, Cardinal is a supplier of sound cards and multimedia upgrade kits, including DSP, digital signal processor, technology that is software upgradable.

a company created through managers buying out RCA's new products division, at bottom what Cardinal really offers to Allen is manufacturing capacity.

As we went to press, Vern Rayburn was acting CEO, and Cardinal still wasn't being mentioned in the same breath as Creative Labs or MediaVision, the dominant multimedia upgrade kit makers.

I meld it to the board.

Does that chip come with its own DSP and a filter?

Sure.

Is that's just the programming language, right, to help in- the chip do its job, correct?

Yeah.

An ESS DAC will have a, um, I don't know how many, a half a dozen different filter options.

Um, and, uh, it's got a rather limited DSP core.

Um, I think it's only a, a few, the maximum is, is a f- few hundred taps.
