Systems-Oriented Network Interface Controller
General Description
The SONICTM-16 (Systems-Oriented Network Interface
Controller)isa second-generation Ethernet Controllerde-
signedto meetthe demandsof today’s high-speed 16-bit
systems.Its system interface operates witha high speed
DMAthat typically consumesless than8%ofthebus band-
width. Selectablebus modes providebothbig andlittle endi- byte orderinganda clean interfaceto standard micro-
processors. The linked-list buffer management systemof
SONIC-16 offers maximum flexibilityina varietyof environ-
ments from PC-oriented adaptersto high-speed mother-
board designs. Furthermore,the SONIC-16 integratesaful-
ly-compatible IEEE 802.3 Encoder/Decoder (ENDEC)al-
lowingfora simple 2-chip solutionfor Ethernet whenthe
SONIC-16is paired withthe DP8392 Coaxial Transceiver
Interface.
For increased performance,the SONIC-16 implementsa
unique buffer management schemeto efficiently process
receiveand transmit packetsin system memory.No inter-
mediate packet copyis necessary.The receive buffer man-
agement uses three areasin memoryfor(1) allocating addi-
tional resources,(2) indicating status information, and(3)
buffering packet data. During reception, the SONIC-16
stores packetsinthe buffer area, then indicates receive
status and control informationinthe descriptor area. The
system allocates more memory resourcestothe SONIC-16 adding descriptorstothe memory resource area. The
transmit buffer management uses two areasin memory:
onefor indicating status and control information andthe
otherfor fetching packet data. The systemcan createa
transmit queue allowing multiple packetstobe transmitted
froma single transmit command. The packet datacanre-
sideonany arbitrary byte boundaryandcan existin several
non-contiguous locations.
Features 23-bit non-multiplexed address/16-bit databus High-speed, interruptible DMA Linked-list buffer management maximizes flexibility Two independent 32-byte transmitand receive FIFOs Bus compatibilityforall standard microprocessors Supportsbigand little endian formats Integrated IEEE 802.3 ENDEC Complete address filteringforupto16 physical and/or
multicast addresses 32-bit general-purpose timer Full-duplex loopback diagnostics Fabricatedin low-power CMOS 132 PQFP package Full network management facilities support the IEEE
802.3 layer management standard Integrated supportfor bridgeand repeater applications
