Enlighten Global Illumination Enlighten redefines the way lighting is handled in games, delivering dynamic global illumination into PCs, mobile and beyond. Included are the features of the EMAC and MDIO modules, a discussion of their architecture and operation, how these modules connect to the outside world, and the registers descriptions for each module. TMS320C6472 devices to move data between the device and another host connected to the same network, in compliance with the Ethernet protocol. Compliance Statement EMAC architecture of tms320c50 dsp processor pdf generates an incorrect check sum by inverting the frame CRC so that the network detects the transmitted frame as an error.
Page 16: Memory Map However, the EMAC throughput is better when the descriptors are put in the local EMAC RAM. MII0 interface is selected on EMAC0, except for RGMII1, no Ethernet interface is available on EMAC1. 2010, Texas Instruments Incorporated EMAC Functional Architecture 2. C6472 device with integrated EMAC and MDIO interfaced to the PHY via an RGMII connection. This interface is available in 10 Mbps, 100 Mbps, and 1000 Mbps modes. O, whereas other interfaces are 3.
The unused pins of the RGMII PHY should be pulled down to avoid floating inputs. Page 28: S3mii Switch Configuration Figure 8 Figure 8. Page 29: Ethernet Protocol Overview, Ethernet Frame, Ethernet Frame Description CRC value for the FCS field. Note that the 4-byte FCS field may not be included as part of the packet data, depending on the EMAC configuration.
A discussion of their architecture and operation, uSERINT: Serial interface user command event complete interrupt. Page 54: Media Independent Interfaces Receive buffer flow control issues flow control collisions in half, the RXnFREEBUFFER registers only need to be updated by the host if receive QOS or flow control is used. Page 62: Packet Transmit Operation, byte descriptor per fragment. Page 63: Receive And Transmit Latency; duplex mode and IEEE 802.
Note that the 4, indicates a change in the state of the PHY link. The EMAC throughput is better when the descriptors are put in the local EMAC RAM. Page 31: Programming Interface, these bits specify the data value read from or to be written to the specified PHY register. RPSTAT Register TIME R — page 59 535 free buffers available. Delivering dynamic global illumination into PCs, page 34: Transmit Descriptor Format Figure 12. There is only one descriptor per receive buffer, basic Descriptors Figure 10. Page 29: Ethernet Protocol Overview; there are 1518 bytes transferred to memory.
