BlueCore3-Multimedia External System
Architecture
BlueCore3-Multimedia External contains the Kalimba
DSP, an open platform digital signal processor (DSP) co-
processor supporting enhanced audio applications.
BlueCore3-Multimedia External has been designed to
reduce the number of external components required,
ensuring that production costs are minimised.
The device incorporates auto-calibration and built-in
self-test (BIST) routines to simplify development, type
approval and production test. All hardware and device
firmware is fully compliant with the Bluetooth v1.2
Specification.
