PS WTF do you think the UMC-1s firmware is so fuxored ehh...
Dude it uses CLs IDE and BS dev software that's ABSOLUTELY HORRIBLE.
If they had gone the EE route you're describing I wouldn't have even posted and I would have thought the EEs at emo et al must be MASOCHISTS considering what they've gone through with CS49700 and CL couldn't even provide a workable "5 chan stereo" or "multi chan stereo" IP boxed with it for god's sake. Just look at the LFE processing and summing DSP IDE FLAWS and it took CIRUS LOGIC not Tonewinner two years to fix that. The LFE summing xover and processing was FUNDAMENTALLY FLAWED on a BASIC SOFTWARE ENGINEERING LEVEL in the MPM and PPM issue abound. The firmware is HORRIBLE. It's obvious the ******** that wrote the software had little to no understanding of xovers summing and generally audio.
THE DSP MICROCODE/FIRMWARE FLAWS ARE A LAUGHABLE JOKE FOR ANY AUDIO ENGINEER WORTH HIS SALT
CL's dev software and support
IS A JOKE COMPARED TO TI!
AN ABSOLUTE JOKE!
M Code seriously give a call to another EE who has actually developed a product using CLs DSPs in an AVR product.
BTW it's a TMS320DA8x the DA7x is a typo. You'd see that it's the one with ARM if you read the spec sheets and whitepapers. I purposely didn't correct that to see if anyone with a brain was reading the whitepapers and would make comment.
PS If your so hot M Code then it's CL that needs you not TW!
Are you are aware that Cirrus Logic's audio DSPs are used by 73% of leading AVR brands, including HK, NAD, Pioneer, Marantz, Onkyo/Integra and Yamaha...
The way the AVR development process works is that the respective silicon maker of the DSP such as TI, ADI, Cirrus Logic and Fujitsu all have their DSP S/W code certified and validated by Dolby and DTS..
Next each individual brand then integrates this certified audio DSP code into their respective AVR/Controller platform including the central CPU controller code...
This is where the majority
of S/W bugs & issues arise, not in the already validated
S/W code by Dolby & DTS. The problem lies with the primary architect/programmer of the system controller S/W not
in the audio DSP code.
If Emotiva has software issues and then blaming Cirrus Logic...
The root problem lies with Emotiva for not
doing a thorough debugging/validation on its own system/platform S/W..
Also if Cirrus Logic did have inherent S/W issues then it would have affected all of the other AVR brands that they supply as well..
For your information, at last count I had personally done AVR product development with multiple brands whose total AVR unit sales exceed 10 million units.. So yes we do know a lot about this subject.
Just my $0.02...
