Abstract
Abstract In a circuit arrangement composed of chips containing highly integrated MOS circuit components for a data processing device, the arrangement including a first chip containing a central arithmetic and control unit, a plurality of further chips each containing a memory, and a bus connecting the chips, each further chip is provided with its own address register for addressing the memory on that chip, and the register is capable of being set to contain any desired address word and to selectively count through a sequence of successive address words under control of counting pulses, each address word identifying a respective word location of the associated memory.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
139 words
In a circuit arrangement composed of chips containing highly integrated circuit components for a data processing device which arrangement includes a first chip containing a central arithmetic and control unit for controlling the operation of said arrangement, at least one further chip containing a memory, and a bus connecting the chips together and including a plurality of data lines connected for selectively transferring the content of an addressed location of the memory to the arithmetic and control unit and transferring signals representing the address of a selected location of the memory to the further chip, the improvement wherein said further chip contains its own address register and means for sequentially varying the contents of its said register by counting pulses, said address register being connected to said bus to permit an entire selected address to be selectively written therein.
Claim 2
Dependent Claim
139 words
In a circuit arrangement composed of chips containing highly integrated circuit components for a data processing device which arrangement includes a first chip containing a central arithmetic and control unit for controlling the operation of said arrangement, at least one further chip containing a memory, and a bus connecting the chips together and including a plurality of data lines connected for selectively transferring the content of an addressed location of the memory to the arithmetic and control unit and transferring signals representing the address of a selected location of the memory to the further chip, the improvement wherein said further chip contains its own address register and means for sequentially varying the contents of its said register by counting pulses, said address register being connected to said bus to permit an entire selected address to be selectively written therein.
Claim 3
Dependent Claim
14 words
Circuit arrangement as defined in claim 1 wherein said circuit componments are MOS components.
Claim 4
Dependent Claim
48 words
Circuit arrangement as defined in claim 2 wherein said bus is connected to said first chip to permit such an entire selected address to be written in to said own address register on said further chip by bit signals conducted from said central unit via said data lines.
Claim 5
Dependent Claim
58 words
Circuit arrangement as defined in claim 3 wherein said central unit is arranged to provide addresses having a number of bits exceeding the number of data lines and said bus further includes a plurality of separate address lines connected for conducting the address bit signals relating to the number of bits which exceed the number of data lines.
Claim 6
Dependent Claim
44 words
Circuit arrangement as defined in claim 4 wherein there are a plurality of further chips each containing a memory and said bus further includes further address lines connected for conducting address signals for selecting the memory of a respective one of said further chips.
Claim 7
Dependent Claim
52 words
Circuit arrangement as defined in claim 4 wherein there are a plurality of said further chips each containing a memory and its own address register, and said bus further includes further address lines connected for conducting address signals for selecting said own address register of at least one of said further chips.
Claim 8
Dependent Claim
42 words
Circuit arrangement as defined in claim 4 wherein said central unit contains an intermediate register and said data lines connect said own address register and said intermediate register for conducting a transfer address to said own address register via said intermediate register.
Claim 9
Dependent Claim
43 words
Circuit arrangement as defined in claim 3 wherein said memory contains at least one transfer instruction containing a transfer address in a predetermined word location and read-out of such instruction causes the address contained therein to be set into said own address register.
Claim 10
Dependent Claim
42 words
Circit arrangement as defined in claim 3 wherein said central unit contains an intermediate register and said data line connect said own address register and said intermediate register for conducting a transfer address to said own address register via said intermediate register.
Claim 11
Dependent Claim
83 words
Circuit arrangement as defined in claim 2 wherein: there are a plurality of further chips each containing a memory and its own address register; said bus is connected between said further chips; and further comprising signal transmitting means connected to be controlled by said central unit for causing the content of a selected location of said memory of one of said further chips to be written in, as a selected address, to said own register of any selected one of said further chips.
Claim 12
Dependent Claim
71 words
Circuit arrangement as defined in claim 10 for carrying out processes in which certain addresses contain a number of bits greater than the number of date lines, wherein said bus further includes a plurality of separate address lines connected for conducting the address bit signals relating to the number of bits in excess of the number of data lines from said central unit to said selected one of said further chips.
Claim 13
Dependent Claim
42 words
Circuit arrangement as defined in claim 11 wherein said central unit contains an intermediate register and said data lines connect said own address register and said intermediate register for conducting a transfer address to said own address register via said intermediate register.
