AMD-640 System Controller Data Sheet
Preliminary Information
GWE#
Global Write Enable
GWE# connects to the global write inputs of the cache SRAMs.
The AMD-640 system controller asserts GWE# off the rising
clock edge during L2 cache line fills to enable the SRAMs to
receive each quadword of the line being returned by the
DRAM controller.
Output
TA[9:0]
Tag Address
TA[9:0] are used to read and write the cache page number to
and from external tag RAM. They function as outputs during
L2 cache line fills and as inputs at all other times.
Bidirectional
TAGWE#
TAG Write Enable
The AMD-640 system controller asserts TAGWE# on the rising
edge of HCLK to enable the L2 cache tag SRAMs to receive the
next tag address.
