82595FX
7.0
FRAME TRANSMISSION
The 82595FX performs all of the necessary func-
tions needed to transmit frames from its local mem-
ory. If Transmit Concurrent Processing is enabled,
the CPU must only program the Base and Host Ad-
dress Register with the starting address to be trans-
mitted, copy a portion of the frame into the
82595FX’s transmit buffer located in local memory
(the number of bytes for this first portion is deter-
mined by the software driver without causing an Un-
derrun), issue a XMT command to the 82595FX, and
complete the data copies for this frame to local
memory. If Transmit Concurrent Processing is dis-
abled, the CPU must copy an entire frame into the
82595FX’s transmit buffer located in local memory,
set up the 82595FX’s Current Address Registers to
point to that frame, and issue a XMT command to
the 82559TX. The 82595FX performs all the link
management functions, DMA operations, and statis-
tics keeping to handle transmission onto the link and
communicate the status of the transmission to the
CPU. The 82595FX performs automatic retransmis-
sion on collision with no CPU interaction.
7.1 82595FX XMT Block Memory
Format
The format in which a XMT block is written to memo-
ry by the CPU is shown in Figure 7-1 for a 16-bit
interface. Figure 7-2 shows this structure for an 8-bit
interface.
