Silicon vendors are under constant pressure to differentiate products. MindTree understands that integration is critical for differentiation; driving both technology advances and changes in market space. MindTree’s BlueWiz IP is explicitly engineered for SoC integration.

The BlueWiz 2.1 BT Silicon IP is a Bluetooth® Baseband controller IP core, for integration with ASICs and FPGAs. BlueWiz is a composite HW-FW implementation of the V2.1+EDR Bluetooth® specifications. The Bluetooth controller firmware includes the HCI transport driver, HCI, LM and link control layers of the lower stack, and an underlying OS abstraction layer. The firmware is written entirely in ANSI C, with straightforward portability to 32-bit CPUs/buses. The Baseband controller has been proven in silicon - in multiple ARM-based SOCs - as well as in products such as mobile phone dongles.






MindTree BlueWiz offers several advantages:

Differentiation

• Interface abstractions and virtual machine environments
• Low Gate count

• Support for 32KHz and 32.768KHz LPO clock
• Low memory footprint
• Scalable MIPS/throughput performance
• Includes CVSD transcoder, PCM a/u-law transcoder digital blocks, and an optional I2S interface for stereo audio codecs

Full Bluetooth technology featured implementation

• BQB qualified for V1.2
• 2.0 + EDR ready, with an upgrade option for 2.1+EDR
• Proven in silicon
• 7 ACL and 3 ESCO/SCO
• Support for Scatternet
• Support for all packet types (including all optional EDR packet types) - A-law, u-law and CVSD voice formats
• Supports Bluetooth® low power modes (Sniff, Hold, Park)

Flexible and configurable interfaces

• Support for SiW1701, Fujitsu, BlueRF and custom RF modems
• Support for AHB and APB bus interfaces and wrappers for 16-bit MPUs and DSPs
• Direct PCM or I2S codec interfaces from Baseband

Reduced time-to-market

As the Bluetooth® market matures, cost reduction is now a primary goal. Available off-the-shelf, MindTree’s BlueWiz Silicon IP has proven integration capabilities, minimizing risks and reducing time-to-market.

Low power consumption

MindTree has designed several power-saving BlueWiz implementations. We ensure a minimal power footprint with:

• Integrated clock and SW-controlled programmable power management
• Multi-level power save modes
• ‘SNIFF’ low power mode
