  • Page 4: Overview

    MA35D1 OVERVIEW MA35D1 is a heterogeneous microprocessor contains a dual-core Corex-A35 and a Cortex-M4. Although MA35D1 is a powerful microprocessor, executing Linux is not that suitable for handling real time event such as motor control. The Cortex-M4 becomes quite handy as a real time processor to process real time events in such scenario.

  • Page 27: Resource Management

    MA35D1 RESOURCE MANAGEMENT In MA35D1, the only resource that is bounded with Cortex-M4 is WDT2 and WWDT2. To prevent contention, MA35D1 use System Security Memory Configuration Controller (SSMCC) to control the memory space that can access by Cortex-M4. And use System Security Peripheral Configuration Controller (SSPCC) to assign the peripherals that are controlled by Cortex-M4.

  • Page 28: Hwsem

    MA35D1 every channel can send 4 words of message each time. WHC provides a TX status register WHCx_TXSTS allowing the sender to know if the data has been read by receiver or not, a RX status register WHCx_RXSTS notify if there’s new message coming in. Besides message exchange, there’s also a WHCx_CPSTS register indicates the counterpart operating and reset status.

  • Page 29: Openamp

    MA35D1 OPENAMP remoteproc Remoteproc is a framework that allows the ARM host processor(s) to load firmware into RTP cores, start the RTP cores, stop the RTP cores, and configure resources that the RTPs might need during their execution (such as configuring and providing shared buffers in DDR memory for message passing). RPMsg RPMsg is a message passing mechanism that requests resources through remoteproc and builds on top of the virtio framework.
