    摘要： A memory system to accommodate two read accesses and one write access in a memory cycle and comprising two groups (11,12) of two independently addressable storage units (126,132; 146,152), each storage unit being addressable by the same spectrum of addresses and each group having a pointer arrangement - (13,14) indicating not more than one storage unit in the group for each address of the spectrum of addresses, by the which it is accessed, together with an input for one of the read addresses and the write address (101,103; 102,103), a data output (129,149) and a data input (133), means (109,124,130; 117. 144,150) to selectively connect the read address connected to a group to that storage unit of the group indicated by the pointer for that address and to selectively connect the data input to the other storage unit, means (128,148) to connect the read storage unit to the data output and means (112,120) to set the pointer for the write address to point to the storage unit of the group used for the writing operation. The generalised case of r reads and w writes is also shown.

    摘要： Scientific data processing apparatus performing three address code operations (102), is responsive to instruction words in successive cycles for generating addresses for a memory (106) storing data objects addressable by r-bit addresses. The memory includes a first (107), a second (109) and a third (112) r-bit address register each having an associated data register (120,125,130) and an associated index register, these latter storing alterable first (118), second (123) and third indices (128) respectively for supply as addresses to the r-bit address registers. Counters (118,123,128) responsive to at least a portion of an instruction word in a cycle independently increment, within the cycle, the indices. Partial base addresses (121,126,131) for the index registers are supplied directly from the instruction word (102). In addition, a means (134) is provided that is responsive to at least a portion of an instruction word in a cycle for independently supplying an arbitrary index within the cycle to at least one of the index registers (118,123,128) to update the corresponding index/indices.
