Unshare Pointer Pragma
Example 6–5. Automatically Shared Master Port
#pragma altera_accelerate connect_variable ptr_a to onchip_memory_0
#pragma altera_accelerate connect_variable ptr_a to onchip_memory_1
#pragma altera_accelerate connect_variable ptr_b to onchip_memory_0
#pragma altera_accelerate connect_variable ptr_b to onchip_memory_1
if (x)
{
}
else
{
}
/* ... perform some dereference operations with ptr_a and ptr_b ... */
#pragma altera_accelerate unshare_pointer my_func/my_ptr
6–6
Nios II C2H Compiler User Guide
ptr_a = ONCHIP_MEMORY_1_BASE;
ptr_b = ONCHIP_MEMORY_2_BASE;
ptr_a = ONCHIP_MEMORY_2_BASE;
ptr_b = ONCHIP_MEMORY_1_BASE;
To overcome this problem, use the unshare_pointer pragma, which
instructs the compiler to always optimize for speed, and never defer
operations for the purposes of resource scheduling. The syntax is as
follows, for a pointer my_ptr in function my_func:
