Asahi Kasei Micro makes dsp ICs such as the AK7755EN. On the website https://www.akm.com/eu/en/products/audio-voice-dsp/lineup-audio-voice-processor/ak7755en/ there is NO and i mean ABSOLUTELY NO information about any tool for programming. i know of audioweaver - which is a third party company but i refuse to believe a chip so complex has nothing in terms of software development. ADI's Sigmadsp has Sigmadsp GUI, TI's Purepath has Purepath studio, cirrus logic has its suite of tools, even Qualcomm CSR has Kalimba DSP dev tools. yet nothing on AKM's lineup of DSPs. Why? just why?
Am i missing something? is this just another case of eastern asian OEM gatekeeping? how is one supposed to code for this dsp? a DSP from AKM has been used in mass production that i know of in the onyx studio 3. so there must be SOME way of coding it. i don't believe Harman Kardon used Audioweaver or did they? did AKM go through the trouble of manufacturing just to hinge their only chance of widescale implementation on a THIRD PARTY?
Please i'm at a loss and need group wisdom. does anyone have ANY experience or idea with these chips - and how to program them? thank you.

Its quite likely that development software is only made available to OEMs who'll buy 100k+ volumes of these chips.
Audioweaver as far as I'm aware only targets ARM CPUs.

Yeah thanks. Honestly I just made the switch to TI’s miniDSP codecs programmed with purepath studio. Turns out the DSP itself isn’t the most capable - only functioning for voiceband, noise cancellation and SUPER basic music processing. The ram wasn’t even enough for the delays needed. But they still have a lot of gate keeping for very little reason.
I went through this and spoke to an AKM engineer in San Jose. He provided sample code in assembly. Detailed manuals with all the hex codes and their functions. But as far as I can tell, it’s for an OEM to provide their own software programming effort and expertise.
Great chips but way above the pay grade for the average DIYer to mess with.
Go with Analog Devices and Sigma Studio Suite. Much easier.
