ARTOS – Audio Real-Time Operating System

Things I’ve worked on, and almost forgotten about.Back in the mid-90’s, I was working at a little Aberystwyth company called Clef Digital Systems. We were designing the software for a thing called the PP-10 Mastering Suite for the renowned Penny+Giles, back when they did audio systems before that side got sold to TLA.

The PP-10 was an audio processing unit based around an Intel i860 RISC chip (to drive the user interface) and a TI C30 DSP. Charles Francis and I wrote an operating system for this beast: ARTOS. From what I recall, I did most of the OS design and code, while Charles did the hard stuff – the more complex DSP algorithms, such as Reverb.

And, believe it or not, the paper we wrote is still available on the net at the AES website. There’s nice.
