Abstract:

A virtual addressing technique for expanding the address space of the EMMY360 to 2 million bytes is presented. The scheme uses a translation table of 512 words of EMMY control store, addressed using bits 2012 of the logical virtual program address. The page table entry reflects status of the referenced page i.e. available, or written to. The semantic pointer for each instruction controls whether a logical address is to be translated, or the execution routine is to use the logical address. Author
