Two main techniques are used for memory management in modern computers and operating systems, as described in this module's readings: paging and segmentation. Sometimes they are combined in a segmentation with paging scheme. Design a memory management scheme for a 50 bit computer architecture, using paging, segmentation or both, as described in this module's readings. Your post should include a clear translation scheme from a 50 bit logical address to a 50 bit physical address including a picture that shows how this translation takes place. In particular, each field of the logical address must be clearly depicted and its length in bits must be specified. The proposed scheme must be at least somewhat realistic; for this reason, simple paging and simple segmentation schemes are automatically disqualified, due to the impossible requirements imposed on the implementation in this case (50 bits addresses)
The microinstructions stored in the control memory of a processor have a width of 26 bits. Each microinstruction is divided into three fields: a micro-operation field of 13 bits, a next address field (X), and a MUX select field (Y). There are 8 status bits in the inputs of the MUX.Calculate the number of bits in the X and Y fields. Also find the size of the control memory in number of words?
Microprocessor(8086) If i write this code Mov ax,[1000] Is this means in the memory directly i will copy what is in the 1000 address if it’s 33 the data that 1000 hold I will say Al is 33 or I should calculate the physical address is which who gives me the data in the 1000 address means I should calculate physical address then if that physical address holds 33 then i say 33 And lastly is there any difference between [1000H] and [1000]
