array of sc_fifo

[David Peng]

Hi, 

I wonder any way to implement an array of sc_fifo with different depth.

I wrote below demo code:

sc_fifo<SomeClass> *s1;

n=4;

s1 = new sc_fifo<SomeClass>[n];

for (int i = 0; i < n; i++) {

  s1[n] = sc_fifo<SomeClass>(("FIFO_"+std::to_string(i)).c_str(), i*1024);

}

It failed that object of type sc_fifo<SomeClass> cannot be assigned because its copy assignment operator is implicitly deleted.

Any suggestion? Or I have to use sc_vector?

Thanks,

David

In your case you have to use the plcaement-new as described here: https://en.cppreference.com/w/cpp/language/new

I would suggets to use C++14 constructs:

std::array<std::unique_ptr<sc_fifo<SomeClass>>, 4> s1;

for(size_t i = 0U; i < n; i++) {
  s1[i] = std::make_unique<sc_fifo<SomeClass>>("FIFO_"+std::to_string(i)).c_str(), i*1024);
}

This one manages the life time of your created objects...
