// Store buffer

//

// It will improve performance by "caching" CPU stores

// using store buffer. This is most important for function

// and all stores would have to complete external WB writes

// to memory.

// Store buffer is between DC and data BIU.

// All stores will be stored into store buffer and immediately

// completed by the CPU, even though actual external writes

// will be performed later. As a consequence store buffer masks

// all data bus errors related to stores (data bus errors

// related to loads are delivered normally).

// All pending CPU loads will wait until store buffer is empty to

// ensure strict memory model. Right now this is necessary because

// we don't make destinction between cached and cache inhibited

// address space, so we simply empty store buffer until loads

// can begin.
