Storage unit and processing system

Abstract

Embodiments of the invention disclose a storage unit. The storage unit comprises at least one single-bit storage structure, wherein each single-bit storage structure comprises four random access memories RAM: a first RAM, a second RAM, a third RAM and a fourth RAM, two read-out ports and two write-in ports; the two read-out ports comprise a first read-out port and a second read-out port; the two write-in ports comprise a first write-in port and a second write-in port; the first read-out port is connected with each of the first RAM and the second RAM, and is used for reading data stored in the first RAM and the second RAM; the second read-out port is connected with each of the third RAM and the fourth RAM, and is used for reading data stored in the third RAM and the fourth RAM; the first write-in port is connected with each of the first RAM and the third RAM, and is used for writing data into the first RAM and the third RAM; and the second write-in port is connected with each of the second RAM and the fourth RAM, and is used for writing data into the second RAM and the fourth RAM. Meanwhile, the embodiments of the invention furthermore disclose a processing system.

Description

technical field [0001] The invention relates to memory technology in the field of hardware, in particular to a storage unit and a processing system. Background technique [0002] With the development of electronic technology, the application of automation is becoming more and more extensive. Generally, the realization of automation is inseparable from the processing system, and the processing system is usually composed of a processor, a memory (Memory), instruments and meters, and a human-computer interaction interface. [0003] In the existing technology, in order to reduce human capital, automation equipment is becoming larger and larger, and the control of large-scale automation equipment involves the storage and reading of massive data. Therefore, in order to meet the control requirements of the processing system, the memory data in the processing system must be increased. storage. In practical applications, it is usually possible to increase the data storage capacity b...

Problems solved by technology

In practical applications, the data storage capacity can usually be increased by increasing the memory access bandwidth. The common method is frequency doubling, that is, by increasing the number of memory accesses per unit time to increase the data access bandwidth. Assuming that the original unit time can store N times of data After frequency doubling, 2N or 3N times of data can be stored per unit time, so the data storage capacity of Memory can be increased, but because the number of accesses that can be increased per unit time is limited, the data storage capacity that can be increased by frequency doubling is also limited, many In some cases, the control requirements of the processing system cannot be met, which limits the application of the processing system
