2.產 品 詳 情 資 料:
LAN DMA傳輸RELIANCE 603515-5A嵌入式控制器包括一個帶DMA控制器的LAN接口。LAN DMA控制器使用FIFO緩沖器將串行LAN總線連接到32位本地總線。FIFO緩沖器允許LAN DMA控制器有效地將數據傳輸到本地總線。82596CA不執行MC68040兼容的突發周期,RELIANCE 603515-5A因此LAN DMA控制器不使用突發傳輸。DRAM寫入周期需要3個時鐘周期(25 MHz)或4個時鐘周期,32 MHz,而讀取周期需要5個時鐘周期。LAN DMA控制器的傳輸速率在25 MHz或32 MHz時為20MB/sec。假設LAN總線上的連續傳輸速率為1MB/sec,則來自LAN總線的傳輸將使用5%的本地總線帶寬。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
