簡(jiǎn)要概述：
Altera公司的三速以太網(wǎng)(TSE)是一個(gè)可配置的FPGA軟核MAC，主要應(yīng)用于10/100 Mbps (快速以太網(wǎng))和1000 Mbps (千兆以太網(wǎng))線路卡、NIC卡以及交換機(jī)等。

官方的FPGA開(kāi)發(fā)套件提供了與Marvell 88E1111 PHY工作的實(shí)例，但俺沒(méi)有銀子，最便宜的DE2開(kāi)發(fā)板也得3000塊吧。我用手頭的EP2C8Q208C8搭建了一個(gè)測(cè)試平臺(tái)：
(1)發(fā)送測(cè)試：
(2)接收測(cè)試：
Id1 = 0x13, Id2 = 0x78e2.
Wait reset.
Reset ok.
config = 0x3100.
MII status = 0x7809.
Reg 4 = 0x1e1.
Wait Auto-nego...OK.
config = 0x3100.
MII status = 0x782d.
MII status2 = 0x4780.
Link OK.

(3) tse 12.1版本已經(jīng)可以支持IEEE 1588V2精密時(shí)間協(xié)議(PTP)協(xié)議。
IEEE1588的全稱(chēng)是“網(wǎng)絡(luò)測(cè)量和控制系統(tǒng)的精密時(shí)鐘同步協(xié)議標(biāo)準(zhǔn)”，是通用的提升網(wǎng)絡(luò)系統(tǒng)定時(shí)同步能力的規(guī)范，在起草過(guò)程中主要參考以太網(wǎng)來(lái)編制，使分布式通信網(wǎng)絡(luò)能夠具有嚴(yán)格的定時(shí)同步，并且應(yīng)用于工業(yè)自動(dòng)化系統(tǒng)?；緲?gòu)思是通過(guò)硬件和軟件將網(wǎng)絡(luò)設(shè)備（客戶機(jī)）的內(nèi)時(shí)鐘與主控機(jī)的主時(shí)鐘實(shí)現(xiàn)同步，提供同步建立時(shí)間小于10μs的運(yùn)用，與未執(zhí)行IEEE1588協(xié)議的以太網(wǎng)延遲時(shí)間1，000μs相比，整個(gè)網(wǎng)絡(luò)的定時(shí)同步指標(biāo)有顯著的改善。
