2.产 品 详 情 资 料：
LAN DMA传输RELIANCE 603515-5A嵌入式控制器包括一个带DMA控制器的LAN接口。LAN DMA控制器使用FIFO缓冲器将串行LAN总线连接到32位本地总线。FIFO缓冲器允许LAN DMA控制器有效地将数据传输到本地总线。82596CA不执行MC68040兼容的突发周期，RELIANCE 603515-5A因此LAN DMA控制器不使用突发传输。DRAM写入周期需要3个时钟周期（25 MHz）或4个时钟周期，32 MHz，而读取周期需要5个时钟周期。LAN DMA控制器的传输速率在25 MHz或32 MHz时为20MB/sec。假设LAN总线上的连续传输速率为1MB/sec，则来自LAN总线的传输将使用5%的本地总线带宽。RELIANCE 603515-5A
LAN DMA Transfers The RELIANCE 603515-5AEmbedded Controller includes a LAN interface with DMA controller. The LAN DMA controller uses a FIFO buffer to interface the serial LAN bus to the 32-bit local bus. The FIFO buffer allows the LAN DMA controller to efficiently transfer data to the local bus. The 82596CA does not execute MC68040 compatible burst RELIANCE 603515-5Acycles, therefore the LAN DMA controller does not use burst transfers. DRAM write cycles require 3 clock cycles at 25 MHz or 4 clock cycles at 32 MHz, and read cycles require 5 clock cycles. The transfer rate of the LAN DMA controller is 20MB/sec at 25 MHz or 32 MHz. Assuming a continuous transfer rate of 1MB/sec on the LAN bus, 5% of the local bus bandwidth is used by transfers from the LAN bus.RELIANCE 603515-5A
