FIELD: computers.;SUBSTANCE: data buffer of cash memory is divided onto two equal pages, one of which in each moment is made active, and another passive, and in case of task change - vice versa, cashing is performed in virtual address space, active portion of data buffer is used with direct address mode, contents of portion of data buffer of old task is kept in main memory independently of processor, and contents of buffer portion of new task is previously restored independently of processor from main memory, global data in restored portion of buffer are synchronized with values changed by other tasks, by means of block for controlling global data.;EFFECT: faster operation and higher effectiveness.;2 cl, 1 dwg
