I don't recall saying that the above is nonsense. I recall saying it cannot make sense until you define the terms "RowAddress", "ColumnAddress" and "BlockAddress". Until that time, it is merely meaningless.

I suggest you consider the name of this newsgroup. It is not comp.intel.architecture.64bit and it is not comp.intel.mmu.64bt

If you want to discuss a specific computational model, you will have to provide some sensible definition of that model. Even with segmented memory, the address space is linear. Even with virtual memory, the address space is linear. Even with paged memory, the address space is linear.

Are you suggesting that current memory architectures are non-segmented, non-virtual, non-paged, non-linear architectures? Are you suggesting that this would somehow become relevant to the theoretical computational model?

While you initially seemed to show some promise, you are beginning to convince me you are nothing but a crank after all.

I call a 1-manifold "linear". What do you call linear? What do you call "bidimensional" ? (Other than some imagined implementation of an SQL table, that is.)

In a computational model, I call any addressing scheme requiring single pointers "linear". On a CPU, I call any address bus consisting of a fixed number of external pins representing the state of some CPU register "linear".

See above. What is linear to you? What is bidimensional? What computational model do you want to discuss? What property of that computational model do you think an OO computational model might improve? Received on Mon Jun 05 2006 - 01:32:31 CEST
