Transcript IAR MakeApp presentation

IAR MakeApp for the Bluetooth
protocol stack
A superior configuration and optimization tool!
1
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
don’t use –> 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!
2
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!

MakeApp ”runtime” environment
- Superior GUI power and flexibility!
Add text or
drawings (like the
LEDs here) to
enhance clarity
Support a Bluetooth stack or other
configurable software blocks
Drag components
from the library
and drop in the
drawing editor
Support MCUs or
external devices

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

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!

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!
