superior configuration and optimization tool!

The importance of tool support

• Most stacks come with no tool support for
  configuration and optimization
• Manual adaptations are needed to use the stack on
  a new H/W or S/W platform
• Most stacks contain code for many features you
  dont use gt waste of memory space!
• Manual optimizations are needed to get a fast and
  compact stack for your project
• You will need training courses or expensive
  consultants
• You will suffer a heavy development cost and
  time-to-market penalty!

The IAR MakeApp tool

• IAR MakeApp is the most powerful Bluetooth
  protocol stack optimization tool ever created!
• Advanced configurations are made within a few
  seconds on a high abstraction level
• The tool generates optimized and adapted
  Bluetooth protocol stacks in ANSI-C
• The stack becomes highly optimized for your H/W
  and S/W platform in seconds
• You save development time, production cost, and
  shorten time-to-market!

Component model- Power and flexibility

• MakeApp supports many types of components, that
  can be added to the same project for
  configuration code generation
• Microcontrollers (8/16/32-bit, DSP)
• External devices (Ethernet, LCD, USB, CAN, ASIC,
  FPGA)
• S/W emulated peripherals (I2C)
• S/W components (Bluetooth or TCP/IP stacks,
  Keyboard scan)
• Unprecedented flexibility MakeApp becomes a
  code generation platform, that can generate
  source code for the complete embedded system!

Stack configuration

• Environment
• H/W (Host CPU, Bluetooth device)
• S/W (RTOS, Compiler)
• Stack features
• Core (HCI, L2CAP, RFCOMM, SDP, ...)
• Profiles (GAP, SDAP, SPP, ...)
• Other (TCI, Message logs, ...)
• Select API functions to implement

Configuration controls code generation
Stack A GAP SDP SPP
Stack B GAP SDP SPP Headset
Stack C GAP SDP SPP Headset (other settings)

• MakeApp helps the user focus on the application
  rather than MCU and stack internals!

ANSI-C code generation

• Code adaptations
• The stack source code is generated for the
  selected H/W and S/W environment
• The generated stack source code only implements
  the selected stack features
• Code optimizations
• Unused features and API functions are removed
  from the stack implementation
• Gives you a very compact stack reduced memory
  usage and faster execution!

Stack optimizer

• Stack source code is generated in ANSI-C.
  Configuration controls the actual implementation.
• Compiler, RTOS and target adaptations can be made
  automatically from GUI configurations.
• Typical optimization situations
• Unused profiles are removed (headset)
• Unused files are removed (BMC)
• Unused features are removed (master/slave role
  switch)
• Unused code is removed (defragmentation/assembly
  of long Msgs)
• Unused functions are removed (unused HCI
  commands)
• The generated stack is tailor made for the
  customer project! No dead-code is included in
  the stack.

11
Code size affect production cost!

• The stack optimizer makes a vertical slice of
  the stack and removes unused code
• The resulting stack becomes very compact and
  waste no ROM space
• Production cost is reduced as CPU and ROM
  requirements are lower!

Time to market is critical delayed launch means
lost market window and reduced sales. Use good
tools to shorten your time to market!

Sensitivity of profits over life cycle
No tool support for stack adaptation
Stack uses too much memory or needs faster CPU
More expensive development tool
