The dual-core architecture with flash memory enables manufacturers to easily differentiate their products with new features without extending development cycles. The enhanced Kalimba DSP coprocessor with up to 120 MIPS, enables more advanced digital signal processing, meeting the high quality audio requirements of stereo headphones, headsets, gaming headsets and soundbars. The audio codec supports 2 ADC channels, up to 6 microphone inputs, stereo output and a variety of audio standards. CSR's popular BlueCore® CSR8670™ and BlueCore5™ Multimedia platforms are software‑portable to the CSR8675, with easy migration of a broad range of solutions from CSR's eXtension™ partners. This enables rapid time-to-market deployment for a broad range of consumer electronic products.
