Two interrupt examples are provided -
|
61 |
|
|
|
62 |
|
|
+ Method 1 does everything in C code.
|
63 |
|
|
+ Method 2 uses an assembly file wrapper.
|
64 |
|
|
|
65 |
|
|
Code size:
|
66 |
|
|
Method 1 uses assembly macros to save and restore the task context, whereas
|
67 |
|
|
method 2 uses functions. This means method 1 will be faster, but method 2 will
|
68 |
|
|
use less code space.
|
69 |
|
|
|
70 |
|
|
Simplicity:
|
71 |
|
|
Method 1 is very simplistic, whereas method 2 is more elaborate. This
|
72 |
|
|
elaboration results in the code space saving, but also requires a slightly more
|
73 |
|
|
complex procedure to define interrupt service routines.
|
74 |
|
|
|
75 |
|
|
Interrupt efficiency:
|
76 |
|
|
Method 1 uses the compiler generated function prologue and epilogue code to save
|
77 |
|
|
and restore the necessary registers within an interrupt service routine (other
|
78 |
|
|
than the RTOS tick ISR). Should a context switch be required from within the ISR
|
79 |
|
|
the entire processor context is saved. This can result in some registers being saved
|
80 |
|
|
twice - once by the compiler generated code, and then again by the FreeRTOS code.
|
81 |
|
|
Method 2 saves and restores all the processor registers within each interrupt service
|
82 |
|
|
routine, whether or not a context switch actually occurs. This means no registers
|
83 |
|
|
ever get saved twice, but imposes an overhead on the occasions that no context switch
|
84 |
|
|
occurs.
