PIPELINE CACHE CONFIGURATION

Note: If pipeline cache is on this board, it is factory installed at 256KB and is not configurable. The location is U6 & U7 and TAG.

CACHE CONFIGURATION
Size	Bank 0	Bank 1	TAG
256KB	(4) 32K x 8	(4) 32K x 8	(1) 32K x 8
512KB	(4) 64K x 8	(4) 64K x 8	(1) 32K x 8
1MB	(4) 128K x 8	(4) 128K x 8	(1) 32K x 8
Note: Depending on board revision, cache will either use this table or the above table. Board will not have both cache configurations.
