Silicon Interfaces 'Bluetooth is a highly integrated Bluetooth BaseBand controller designed to form the heart of Bluetooth wireless communication systems. Bluetooth is an innovative new technology in today's wireless communications market, which will enable the wholesale replacement of many of the short-range cables we use today. The Bluetooth wireless protocol allows for easy communication between all mobile devices, including cell phones, laptops, PDAs, wireless headsets, digital cameras and more. Embedded software group at Silicon Interfaces have started to work on TI DSP implementation for SI23BTB20 with EDR targeted to audio markets. SI23BTB20 bluetooth baseband controller provides fast and secure transmission of data/voice within a given range.
The SI23BTB20 Bluetooth Baseband Controller implements EDR(Enhanced Data Rate) operation as defined under the Bluetooth 2.0 specifications. It implements baseband and host controller interface (HCI) of the Bluetooth protocol and is specifically designed to meet the immediate market needs for low-power Bluetooth applications. The on-chip peripherals provide easy interfacing to a Bluetooth radio and to a host system.
The modulation techniques and additional packet types that allow us to deliver a peak rate of 3 Mbps (2.1 Mbps real throughput) over a Bluetooth connection. Our EDR implementation allow us to achieve the data rate; the power consumption; the user experience and with very minimal impact on the upper layers. The SI23BTB20 support backward compatibility with our earlier versions of Bluetooth v1.1 and v1.2 as a result of which we have maintained in our design, different modes of operation for the link, and create a new message that EDR compatible radios exchange to switch between modes. The core enables system-on-a-chip (SoC) developers to incorporate Bluetooth wireless technology in an ASIC or ASSP with low risk and fast time to market. SoC designers can have access to a verified building block to quickly design unique solutions that provide a competitive edge for today's marketplace. Figure below shows the functional block diagram of the Bluetooth BaseBand controller core, along with key interfaces of the core design. The core is attached to an on-chip processor through an AMBA-based bus interface. A fully digital radio interface provides connectivity to Bluetooth radio product.

Bluetooth Block Representative Schematic:
Host Interface: The functionality this block is to interface the BaseBand block with Host side i.e. with LM. The interface is compatible with AMBA. The information data is exchange between Host and BaseBand
Tx and Rx Data Path Unit: The information data is collected from Host Interface for the Packetisation of data. The process of Packetisation includes the Access Code and Packet Header generation as well as applying error correction, detection and validation schemes on information data. While reception data packet is received from Radio module, which includes the decoding of Access Code, Packet Header and also performs error correction, detection and validation schemes. HEC and CRC are used for data validation and FEC is used for error correction and detection.
Encryption: The Encryption block includes the encryption engine, which generates the cipher bit stream. This bit stream is XORed with input stream to produce the encrypted output. Encryption is done for the security purpose.
Packet Controller: The main function of this block is to activate and deactivate the operation of modules inside Data Path block depending upon the Packet Type.
RF Interface: Bluetooth Radio module is interfaces with BaseBand through this block. The RF Interface is fully digital and is used to program the Control Status Register of Radio module.
