Abstract:
1. A method for associating, with a first address, a second address of reduced size for directly addressing a context memory on a computer, comprising: a) calculating a first intermediary address using a reduced number of bits of the first address, the first intermediary address having a reduced size with respect to the first address; then b) choosing as a second address the first intermediary address if this second address is not associated with another first address, or, otherwise, c) calculating a second intermediary address by a first polynomial division of the first address, the second intermediary address having a reduced size as compared to the first address; then d) choosing as a second address the second intermediary address; wherein the first address comprises a device address, of a number n of bits, associated with a device, and a network address, of a number m of bits, and further comprising the step of: i) comparing the network address with a predetermined group of accepted network addresses and, if the network address is an accepted network address, associating a network sub-address, of a number p of bits, with the network address, where number p is smaller than number m; wherein the first intermediary address comprises a number q of bits, where number q is smaller than number n and greater than number p, and step a) comprises the steps of: a1) choosing for each bit of rank from a2) choosing for each bit of rank from p+1 to q−1 of the first intermediary address each bit of same rank of the device address; and a3) setting the bit of rank q of the first intermediary address to 0.
