Note: The coefficients match those from the datasheet, and its addendum, with
|

the exception of the energy table. The energy table on the datasheet (and in
|

the QV5220.COD from qboxpro) lists it in RMS notation which doesn't help us
|
||||
since I(Lord Nightmare) can't figure out the proper formula TI used for
|
||||
converting energy to RMS (the obvious 'take all the values in the chirp ROM,
|
||||
multiply them by 1/2/3/4/etc, square each one, sum them up, divide by 51,
|
||||
which is # of ROM entries in chirp ROM, and take the square root of the
|
||||
result', doesn't QUITE work. It almost does, if you add 16 to the result, for
|
||||
the first 4 entries, but beyond that the entries become farther and farther
|
||||
offset).

/* The following TMS5220C coefficients come from the tables in QBOXPRO, a
|
||||
program written at least in part by George "Larry" Brantingham of Quadravox,
|
||||
formerly of Texas Instruments, who had laid out the silicon for the
|
||||
TMS5100/TMC0280/CD2801. It is the same as the TMS5220 but has a change in
|
||||
the DAC layout which improves the sound quality, as well as having a proper
|
||||
external reset (pull /WS and /RS low at once) and having support for 4
|
||||
different frame lengths (either the usual 8 interpolations, or shorter frames
|
||||
with 6,4,or 2 interpolations only).
|
||||
Note: the energy table in QV5220.COD is also in RMS and was not used (it also may well be incorrect; the values in QV5220.COD have an offset by one index which looks wrong), instead the table from the 5200/5220 is used here.
|
||||
Note: the Kx tables are taken directly from QV5220.COD but with /64 added to each value as the values are stored ranging from -32768 to 32767 in QBOXPRO instead of -512 to 511 as on the real chip.
|
||||
***These values have not yet been verified against a real TMS5220C, see below as for why***
|
||||
This has not yet been verified against a real TMS5220C, and doing so will require decapping one as the TMS5220C, unlike the TMS5220, has a nonfunctional PROMOUT pin. This makes reading the internal LPC tables out electronically (via PROMOUT) impossible.
|
||||
This decapping has now been accomplished, but the verification has not been completed yet.
