CMSIS
|
|
|
|
The ARM Cortex Microcontroller Software Interface Standard (CMSIS) is a
|
|
vendor-independent hardware abstraction layer for the Cortex-M processor
|
|
series and specifies debugger interfaces. The CMSIS enables consistent and
|
|
simple software interfaces to the processor for interface peripherals,
|
|
real-time operating systems, and middleware. It simplifies software
|
|
re-use, reducing the learning curve for new microcontroller developers
|
|
and cutting the time-to-market for devices.
