Q And, Mr. Norris, at the time that figure 1 was created,
could you store an analog signal as digital data without
converting it?
A No. You couldn't store the analog signal, either.
Q So in order to get something ready for storage, we'v got
to do something to it; is that right?
A A whole bunch of processing.
Q Okay.
What else do we need -- using figure 1, what else do
we need to do by way of processing to get the analog signal into a form that can be stored as digital data?
A After you've conditioned the analog signal in block 22, thenext thing to do is to convert it to digital.
After it's converted to digital, then it's ready to be
compressed. So that you use up less of your memory space inthat digital form, when it makes its way to the flash memory.
All of those steps are various forms of processing.
Q And at this time, when figure 1 was created, were you aware of any technology that would allow you to convert analog signals to digital data and to process it without using memory?
A No. Not possible.
Q And once the signal was processed with respect to figure 1,then what would happen?
A That's one-half of the equation. The other half is that,
unlike RAM, which stores bits of memory, flash stores
information in discrete blocks.
Suppose you've made a recording but didn't fill up an
entire block. You start another recording or you want to maybeerase the previous one. We had to deal with the issues of not tossing a block away because it was filled with some information from this recording and some information fromSo management of all that was new at the time to flash memory. And we had to deal with that in order to efficiently make use of this media called flash to be useful to us.
Q And with respect to figure 1, was the flash memory 29,
that's reflected in the block diagram, is that where the
digital data was stored once it had been processed?
A Yes, sir.
Q So we have to process; then we have to store?
Q Do you have an understanding as to whether compression
circuitry, coupled to the memory circuitry for compressing digital data for storage, whether or not that process, at the time that this was written, would have involved the use of RAM?
A It was exclusively RAM.
The flash memory module is distinct from the other
memory that was used for all this processing stuff.
MR. JAMESON: No further questions, Your Honor. Thankyou.
