The operations on Core 0 are:
Write Flag at shared memory
If(Cache is enabled for access shared memory)
{
If(L2 Cache Size>0)
{
CACHE_wbL2(flag address, size of flag);
}
Else if(L1D Cache Size>0)
{
CACHE_wbL1D(flag address, size of flag);
}
}
The operations on Core 1 are:
If(Cache is enabled for access shared memory)
{
If(L2 Cache Size>0)
{
CACHE_invL2(flag address, size of flag);
}
Else if(L1D Cache Size>0)
{
CACHE_invL1D(flag address, size of flag);
}
}
If(Prefetch buffer is enabled for access Core X’s L2 RAM)
{
Invalidate Prefetch Buffer;
}
Read Flag at shared memory
大家好，这段伪代码在实际编程中怎么写，刚接触多核处理器，我的板子是6670和6678的，请各位帮忙解答，谢谢大家。
