Factors Driving Medical Electronics
Consistent market growth, strong global trends driving future
Aging populations
• By 2020 double the people will be over 60 years old
as in 2000
Rising healthcare costs
• U.S. healthcare spending more than 15% of GDP, Europe not far behind
• Costs expected to grow from $2 trillion in 2007 to $3.1 trillion in 2012
Remote and emerging markets
• China healthcare expenditure increased from 3.7%
of GDP in 1995 to 5.6% in 2007
• India government proposed in 2008 to increase public
expenditure on health care from 1% to 3% of GDP
Personal healthcare
• 33% of medical semiconductor revenue in 2008
went into consumer medical devices

What is ARM® Cortex™-M3?
• The Cortex family of ARM processors provides a range of solutions optimized around specific market
applications across the full performance spectrum.
• Cortex underlines ARM's strategy of aligning technology around specific market applications and
performance requirements.
• The ARM Cortex family is comprised of three series, which all implement the Thumb-2 instruction set to
address the increasing performance and cost demands of various markets:
– ARM Cortex-A Series,
• Applications processors for complex OS and user applications.
• Supports the ARM, Thumb and Thumb-2 instruction sets.
– ARM Cortex-R Series
Did You
• Embedded processors for real-time systems.
Know?
Texas Instruments
• Supports the ARM, Thumb, and Thumb-2 instruction sets
is the lead partner
– ARM Cortex-M Series
for ARM Cortex
• Deeply embedded processors
A8, R4, and M3!
• optimized for cost sensitive applications.
• Supports the Thumb-2 instruction set only
Note:
• ARM Code 32-bit instructions / 32-bit data
• Thumb Code 16-bit instructions / 32-bit data
• Thumb-2 Code mostly 16-bit & some 32-bit (25% Faster, 26% Smaller)
