Shared parallel data reading-writing apparatus of multi memories among multi controllers, and reading-writing method of the same

Abstract

The invention provides a shared parallel data reading-writing apparatus of multi memories among multi controllers, and a reading-writing method of the same. The shared parallel data reading-writing apparatus of multi memories among multi controllers includes a plurality of processor units and a plurality of storage units, wherein each storage unit is corresponding to each arbitration unit; each processor unit is corresponding to an address partition unit and a read data acquisition unit; aiming at the situation that the plurality of processor units access one storage unit at the same time, the arbitration unit can be used for carrying out arbitration management on a data operation request; and only the data operation request satisfying the preset conditions is selected; and the corresponding storage unit is used to execute data operation. As the processor units can directly access the storage units according to the addresses distributed by the address partition units, higher bandwidth can be provided; the operating performance of the processors can be satisfied; and the data access efficiency is greatly improved. Besides, the data exchange redundancy problem among the plurality of processors can be solved, so that the shared parallel data reading-writing apparatus of multi memories among multi controllers has wide market prospect in the integrated circuit field.

Description

technical field [0001] The invention relates to the field of integrated circuits, in particular to a multi-controller multi-memory shared parallel data read-write device and a writing and reading method thereof. Background technique [0002] With the development of science and technology and the progress of society, integrated circuit design has been widely used, and more and more electronic devices have entered people's daily life, which not only brings convenience to people's daily life, but also further promotes the development of science and technology. Innovation and R&D. In the field of integrated circuit design, data reading and writing is one of the important items. [0003] Processors often have ultra-high computing power and can perform fast calculations on data in a short period of time. In order to maximize the computing power of the internal computing unit of the processor, RAM coupled to it is usually configured as an internal memory to improve data access ef...
