    摘要: Memory module selection and reconfiguration apparatus in a data processing system wherein a modular working memory formed by a plurality of memory modules sends during the sytem initialization to a central processing unit information related to the capacities of the constituting modules (Ml, M2, M3, M4).
    The central unit processes such information and provides through a channel (30) the memory with a set of information representative of the capacity of the first module (G1), of the sum of the capacities of the first and second module (G2), of the sum of the capacities of the first, second and third module (G3) and so on, up to the total capacity of the working memory.
    This information set is stored into registers (31, 32), each one related to a possible module, of a module selection unit included inside the working memory.
    When the memory is addressed, a most significant address portion (BA 03 - 06) is compared at the same time by several comparators (33, 34, 35, 36), one for each register, with the content of the several registers.
    The comparison result signals in output from comparators are applied to a decoder (37) which, in function of such signals, generates signals selecting one among the several memory module.
    The module selection unit is carried out by means of simple and fast circuits so that the module selection time is very short.

    摘要: Digital timing unit for timing data processing systems or units thereof, wherein the output signals of a shift register are applied to a plurality of EXCLUSIVE OR gates (G 1 ) .... (G n ).
    The shift register, at first in a known status, is activated so that an electrical transition is shifted through the register cells and defines a timing cycle, at the end of which the register is set in a second known status.
    A feedback and control logic (3, 4, 5, 6, 7, 8, 9) allows to activate the register independently from its status and to keep it in the status occuring at the end of a timing cycle until a new start signal is received.
    The shift of the register is caused by timing pulses generated by an oscillator (1).
    The timing signals generated by the timing unit and present on the outputs of the EXCLUSIVE OR may be modified, as to the length, by changing the oscillator period and/or the connection between the EXCLUSIVE OR inputs and the outputs of the shift register.
