# funreg: Functional Memory-mapped Register I/O
|
|
|
|
|
|
|
|
|
|
*funreg* provides a functional approach to operating on memory-mapped registers
|
|
|
|
|
with zero overhead. This library primarily targets embedded firmware, where
|
|
|
|
|
these types of operations are frequently encountered.
|
|
|
|
|
|
|
|
|
|
What makes this library unique is its ability to carry out multiple register
|
|
|
|
|
operations with a single function call, reducing this to a single register read
|
|
|
|
|
and write. Further, registers can be organized into "groups": these groups can
|
|
|
|
|
receive a list of operations for any of the contained registers, and will
|
|
|
|
|
optimize down to a single read and write for each register.
