Overview
PE-GMAC0from Alcatel provides Gbps Ethernet Media Access Controller (MAC) incorporation customer's ASIC design. PE-GMAC0 module several features including support wide range physical layer devices full-duplex capability. PE-GMAC0 module consists nine sub-modules. These sub-modules comprise transmit receive portions Ethernet plus sub-modules supporting devices, host interface, clocks resets. These sub-modules connected together with additional modules make Gbps Ethernet controller. There many different possible applications PE-GMAC0, including network interface designs, Ethernet switching designs, test equipment designs. PE-GMAC0 module designed Verilog provided licensees with behavioral testbench. This silicon-proven soft core first shipped 1996, since been licensed over dozen organizations. design synthesized .5µm CMOS better). nominal module size approximately 35,000 gates.

PE-GMAC0 Gigabit Ethernet Soft Core
Structure PE-GMAC0 module consists range sub-modules shown adjacent diagram). sub-modules thought groups: functions supporting network functions. functions principally provided transmit receive modules. These modules must included every implementation. These blocks also include transmit receive state machines. supporting functions provided 8B10B Assembler Dis-assembler blocks. system side, provides 32-bit parallel data streams, transmit receive. There also several control signals associated with data transfer 32-bit data streams. general-purpose nature data stream allows PE-GMAC0 module work equally well multiple-MAC designs such switches single applications such embedded interfaces workstations. Standards Support PE-GMAC0 supports both IEEE 802.3z Gigabit Ethernet specification 802.3x Full Duplex Flow Control. IEEE 802.3x formally recognizes Full Duplex part Ethernet standard specifies Full-Duplex pause control. This feature allows overloaded Ethernet node send pause frame request link partner node temporarily stop sending data. This enables overloaded node partially empty buffer. PE-GMAC0 module supports recognition generation Pause Frames. PE-GMAC0 also supports asymmetric Flow Control. IEEE 802.3z specifies encoding Fiber-Channel FC-1 layer. Above layer FC-1, however, substitutes Ethernet layer IEEE 802.3. This Fiber-Channel layer makes possible develop high-speed system without risk associated with developing completely untried (physical) layer.

Layout PE-GMAC0 module
Application PE-GMAC0 exports 4-byte packed transmit receive packet streams directly design, thereby allowing customer-specific solutions readily connected core. This turn allows core's performance tailored optimized each individual application. create complete system, with industrystandard SERDES must added. PE-GMAC0 designed nominal 1.25 Gbps yield Gbps delivered data. PHYs with SERDES available that 1.25 Gbps (though from Inventra).
