Method and circuit for accessing write data path of on-chip memory control unit

Abstract

The invention discloses a method and circuit for accessing a write data path of an on-chip storage control unit. The method comprises that: a target controller sends a write address and write data to a write data path interface; the write data path interface sends a write address and write data to the address conversion unit; the address conversion unit sends the target address and the write data to a plurality of storage control units, and determines a target storage control unit; the address conversion unit obtains a feedback signal of the target storage control unit and sends the feedback signal to the target controller; and if the feedback signal is writable, the target controller sends a write signal to the target storage control unit, and the target storage control unit stores the write data after receiving the write signal. According to the technical scheme, data transmission is controlled through the data flow between the write data path interface and the target controller, the bit error rate and the packet loss rate can be reduced, and the reliability of write operation is improved.

Description

technical field [0001] The invention belongs to the technical field of integrated circuits, and in particular relates to a method and a circuit for accessing a writing data path of an on-chip storage control unit. Background technique [0002] DAG (Direct Acyclic Graph) directed acyclic graph technology is widely used in the blockchain field, especially in the proof-of-work algorithm. DAG is the encrypted information of all blocks on the blockchain, and its volume gradually increases with the development of the blockchain. The workload proves the chip, and the data that the calculation depends on is the DAG file. Therefore, before computing on the chip, it is first necessary to write the DAG into the memory space of the chip. In order to solve the above technical problems, in the existing technical solution, the host computer sends the entire DAG to the computing chip through a high-speed bus. While receiving data, the computing chip completes protocol analysis internally...

Problems solved by technology

[0003] However, the existing solutions have the following problems: 1) There is no data flow control for writing data path, there is the possibility of packet loss and bit error, and the reliability is poor; 2) The control right of writing data path cannot be flexibly configured; 3) If If the storage unit has a damaged area, the stored DAG data will be damaged, which will increase the error rate and reduce the computing power of the computing chip.
