2.数组汇编
/*------------------------------------------------------------------------*/
typedef void (*ASMCodeArray_FPtr)(void);//定义数组可执行汇编的函数指针
int main(void)
{
HotBIOS_State iState;
TI_IREG AsmCodeArray_IsrFunction[]=//汇编数组首地址实际为汇编入口地址
{//下面的"数据"实际为汇编代码
ASMCode16i(ASMCODE_POPM_A),//psha
// ASMCodeArrayEx(ASMCODE_B_K, Tsk_F_isr),//b Tsk_F_isr
__asm_goto__(Tsk_F_isr),
ASMCodeArray(ASMCODE_LD_k_A, 0x01u),//ld #1, a
};
TI_IREG AsmCodeArray_Function[]=//汇编数组首地址实际为汇编入口地址
{//下面的"数据"实际为汇编代码
ASMCode16i(ASMCODE_PSHM_A),//psha
//bd xxxh ->loop
// ASMCodeArrayEx(ASMCODE_BD_K, &AsmCodeArray_IsrFunction[1]),//bd AsmCodeArray_IsrFunction
// ASMCodeArrayEx(ASMCODE_B_K, &AsmCodeArray_IsrFunction[1]),//bd AsmCodeArray_IsrFunction
__asm_goto__(&AsmCodeArray_IsrFunction[1]),
ASMCodeArray(ASMCODE_LD_k_A, 0x01u),//ld #1, a
};
//声明函数指针ASMCodeExec来实际运行数组内的汇编代码
ASMCodeArray_FPtr ASMCodeExec = (ASMCodeArray_FPtr)AsmCodeArray_Function;
ASMCodeExec();//调用数组内的汇编代码
3.在MCU/ARM/DSP上实现动态链接
哈哈~~数组要比代码好管理(删除,移动,变换,加密等等)的多~~~
