In 1994 Ericsson initiated a study to investigate the In 1994 Ericsson initiated a study to investigate the feasibility of a low-power low-cost radio interface feasibility of a low-power low-cost radio interface between mobile phones and their accessoriesbetween mobile phones and their accessories

In Feb 1998, five companies Ericsson, Nokia, IBM, In Feb 1998, five companies Ericsson, Nokia, IBM, Toshiba and Intel formed a Special Interest Group (SIG)Toshiba and Intel formed a Special Interest Group (SIG)

In July 1999 the first bluetooth specification 1.0 was In July 1999 the first bluetooth specification 1.0 was releasedreleased

MIPS requirements of Bluetooth stackMIPS requirements of Bluetooth stack+ Baseband Layer (LC, LM and HCI): 8-12MIPS

+ Host Protocol Layer (HCI, L2CAP, RFCOMM, SDP):1-2 MIPS

+ Application layer and profiles: 1-20MIPS

+ High speed point to multipoint with 7 connections 20MIPS


Microprocessor considerations – The challengeMicroprocessor considerations – The challenge

What drives Bluetooth developmentWhat drives Bluetooth development+Drive towards <$5 per IC+Low power IC’s+Majority applications in cell phone market+Majority of uses are point to point voice or data

Why single chip point to multipoint not availableWhy single chip point to multipoint not available+Multipoint needs more powerful embedded link control

processor but this drives up the cost of the IC+More powerful embedded processor normally requires

more power+Applications are not demanding it yet
