Description

Verify and review (if needed) the scalability of memory in the simulator for large memory ranges (address space for 48 and 64 bit addresses).

Question:

o ISPRAS to review and confirm the sparseness of the implementation of memory
• Does memory use of generation scale with number of locations touched or the range of (min, max)

Answer

In the current implementation of the simulator, memory is divided into 4KB regions which are allocated only when touched (written to).

Check whether the current way to avoid excessive memory consumption is sufficient. This includes more intensive testing. If not, the algorithm must be reviewed.
