Abstract

The invention discloses a rate-adaptive storer interface circuit. According to the rate-adaptive storer interface circuit, a purpose that sending control signals are generated according to sending rates of all channels is achieved through a sending rate control module. The rate-adaptive storer interface circuit achieves sending rate self-adaption of communication links through the sending rate control module, compared with a constant-rate interface, the sending rate is flexible and configurable, and a time-division multiplex access method is utilized to maximize efficiency and data throughput rate of a COMI interface. The rate-adaptive storer interface circuit can be applied among all the communication links and an internal storer at the same time.

Description

technical field [0001] The invention belongs to the field of interface circuits, and in particular relates to a rate-adaptive memory interface circuit. Background technique [0002] General bus control devices have an external memory interface. Because the internal storage space of the bus controller is limited, the internal storage space is expanded by providing an external memory interface connected to a single-chip memory for data processing. send and receive. For example, the transparent mode of the 1553B bus controller provides an interface for external memory, but because the 1553B bus rate is fixed, this interface only provides a fixed rate. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned disadvantages, and provide a rate-adaptive memory interface circuit with flexible and configurable sending rate. [0004] In order to achieve the above object, the present invention includes an internal receiving synchrono...
