Problems solved by technology

In some applications (such as: multimedia playback), each data (such as: 8K image frame data) must be delivered to the target program (such as: multimedia player program) within a certain time, otherwise there will be hysteresis; if eac

Example Embodiment

[0010] figure 1 An example of a data transmission system of the present disclosure is shown. figure 1 The data transmission system 10 can speed up data transmission between the two system single-chip (SOCs), including a master system single-chip (master SOC) 100 and a slave system single-chip (dependent SOC) 200; this specification, terms "Master" and "Subject" are used to help description, and there is no dependency between the two system single-chip 100, 200, which does not require the communication protocol between the two system single-chip 100, 200. Certainly. The master SOC 100 (eg, video decoding SOC) contains a main control loop buffer 110 and a master receiving ring buffer 120. The slave SOC 200 (eg, video playback SOC) contains a slave receiving ring buffer 210 and a slave transceiving ring buffer 220. The slave receiving annular buffer 210 is substantially synchronized with the write pointer of the main control conveying ring buffer 110, and the read pointer of the two...

Abstract

The invention discloses a data transmission system, a circuit and a method. The data transmission system can accelerate data transmission between single chips of two systems. The data transmission system comprises: a master control system single chip, which comprises a master control transmission circular buffer and a master control receiving circular buffer; and a slave system single chip comprises a slave receiving circular buffer and a slave transmitting circular buffer. The slave/master receive circular buffer is a copy of the master/slave transmit circular buffer so that write pointers of the two buffers are substantially synchronized and read pointers of the two buffers are substantially synchronized. According to the above, the read-write operation of the master/slave transmission circular buffer can be regarded as the read-write operation of the slave/master receiving circular buffer, so that a data replication program of a part of the data transmission can be omitted to accelerate the data transmission.

Description

technical field [0001] The present disclosure relates to a data transmission system, circuit and method, in particular to a data transmission system, circuit and method suitable for data transmission between two SoCs. Background technique [0002] The general USB transmission process includes: the transmission end (TX) program copies the data to the TX transport layer; the TX transport layer wraps the data and sends the data packet to the TX USB driver; the TX USB driver sends the data packet to The receiving end (RX); after the RX USB driver receives the data packet, it is sent to the RX transport layer; the RX transport layer unravels the data packet and distributes the data to the target program. During the above transmission process, the data will be copied multiple times. In some applications (such as: multimedia playback), each data (such as: 8K image frame data) must be delivered to the target program (such as: multimedia player program) within a certain time, otherw...
