Detect RAMs from static arrays

[JulianKemmerer]

As opposed to making users specify RAM ~template functions

Ex. see

  static uint32_t my_ram[N];
  uint32_t rd_data1 = my_ram[addr1];
  uint32_t rd_data2 = my_ram[addr2];
...
  if(wr){
    my_ram[wr_addr] = wr_data;
  }

And infer a RAM with two read ports and one write port

[JulianKemmerer]

Need to take into account how many times writes and reads occur to the RAM and what order they occur in read first write first etc

And properly wire data flow to a module like ram template are - has feedback wires :-/

[JulianKemmerer]

Hows this syntax?

typedef struct a_dual_port_ram_t {
    uint32_t read(uint32_t addr);
    void write(uint32_t addr, uint32_t data_in);
    uint32_t the_ram[128];
} a_dual_port_ram_t;
void my_func(uint32_t raddr, uint32_t waddr, uint32_t wdata) {
  static a_dual_port_ram_t my_ram;
  uint32_t rdata = my_ram.read(raddr);
  my_ram.write(waddr, wdata);
  return rdata;
}
