34 Two interrupt examples are provided -
36 + Method 1 does everything in C code.
37 + Method 2 uses an assembly file wrapper.
40 Method 1 uses assembly macros to save and restore the task context, whereas
41 method 2 uses functions. This means method 1 will be faster, but method 2 will
45 Method 1 is very simplistic, whereas method 2 is more elaborate. This
46 elaboration results in the code space saving, but also requires a slightly more
47 complex procedure to define interrupt service routines.
50 Method 1 uses the compiler generated function prologue and epilogue code to save
51 and restore the necessary registers within an interrupt service routine (other
52 than the RTOS tick ISR). Should a context switch be required from within the ISR
53 the entire processor context is saved. This can result in some registers being saved
54 twice - once by the compiler generated code, and then again by the FreeRTOS code.
55 Method 2 saves and restores all the processor registers within each interrupt service
56 routine, whether or not a context switch actually occurs. This means no registers
57 ever get saved twice, but imposes an overhead on the occasions that no context switch
