PCIE-to-SATA polymorphic low-delay adaptive circuit

Abstract

The invention discloses a PCIE (Peripheral Component Interface Express)-to-SATA (Serial Advanced Technology Attachment) polymorphic low-delay adaptive circuit, which belongs to the field of integrated circuits and comprises a reset module, a clock module, a configuration module, a debugging module, a PCIE data receiving and processing module, an SATA data processing module, an SATA data transceiving module and a rate adaptive module. The reset module is used for resetting the circuit; the clock module provides a working clock; the configuration module provides a circuit configuration function; the debugging module provides a chip debugging function; the PCIE data receiving and processing module realizes PCIE data receiving, transmitting and processing functions; the SATA data processing module is used for SATA data processing; the SATA data transceiving module realizes data transmission and receiving functions of SATA and PCIE (Peripheral Component Interconnect Express); and the rate adaptive module automatically adjusts the transmission communication capability of the PCIE after analyzing and operating the transmission rates of the PCIE and the SATA. The PCIE-to-SATA polymorphic low-delay adaptive circuit provided by the invention has the advantages of polymorphism, low delay, self-adaption, high channel, high bandwidth, multiple channels and real-time performance.
