Is this an example of a co-routine?

[c_weed]

I am trying to figure out what a co-routine is and is it a block of assembly code that performs one function?

...
LDMFD{sp!, R0-R4}

Label: start_of_function
STMFD{sp!, R0-R1}
Label: jump_here
MOV R0, #1
ADD R1, R0, R0
branch =x
swi 0x11
LDMFD{sp!, R0-R1}

STMFD{sp! R0-R3}
bl come_here
...

Would the code between

STMFD{sp!, R0-R1}

and

LDMFD{sp!, R0-R1}

be considered a co-routine (but not a subroutine since it has multiple points of entry)?

A coroutine is a path that can be stopped/interrupted and later started/resumed. Anything from a thread to an iterator can be seen as a coroutine. It's pretty broad in it's usage. Don't let "multiple entry points" throw you off.
