As cabin audio becomes a way to separate trims, the SKY4680x bets that automakers want one software base scaling across the range
Skyworks Solutions has launched the SKY4680x, a range of digital signal processors (DSPs) for car audio with one, two or three cores sharing a single software environment from entry-level to premium vehicles. The launch takes the chipmaker past its radio tuners and digital radio chips into dedicated in-car audio processing.
The three-core variant combines Cadence HiFi 5 cores for over 1.2 GHz of combined processing, and some versions add a customer-programmable Arm Cortex-M3 microcontroller. With 8 MB of on-chip memory, the DSPs can run without external memory in supported designs, which Skyworks says lowers cost, power draw and exposure to volatile memory supply.
Common code across the range lets automakers and suppliers match audio features to each trim without rewriting software between programmes. The chips handle up to 64 audio channels and accept customer algorithms, third-party audio software and Edge AI tasks, with samples and evaluation boards out now.
In a statement, Vivek Subramanian, Vice President of Product Line Management for Audio, Infotainment and Gaming at Skyworks, said: “Automotive audio systems are evolving beyond traditional sound processing as automakers seek greater flexibility to deliver sophisticated in-cabin experiences, incorporating their own innovations and technologies from external partners. The SKY4680x family helps customers meet these evolving requirements while accelerating development and deployment across vehicle programs.”
