摘要
A method and apparatus for determining what programme shall utilise a rapid access memory in a computer working with a plurality of programmes and having a conventional slow access (NM) memory and a rapid access memory (CM), characterized in that during a test period there registered for each programme the number of instructions in the programme requiring access to the memory, this number being divided by the whole memory space required by a programme, the quotients formed after each other in this way being compared with each other and for the programme with the highest quotient the memory content is transferred from the slow access memory to the rapid access memory. For each programme there is registered with the aid of a counter means (RF) the number of instructions requiring access to the slow access memory (NM). This number is divided with the aid of a measuring circuit (R1, R2, JR, KB) by the entire memory space for the respective programme noted in a space memory (SM). For the programme with the highest quotient the memory content is transferred from the relatively slow access memory (NM) to the rapid access memory (CM). An address memory (AM) is arranged, and for the programme information transferred from the slow access memory (NM) to the rapid access memory (CM) the address memory reads out the starting address of the programme information in the rapid access memory (CM) on addressing a starting address in the slow access memory (NM)
