Level 1 Cache
The Model 170 uses a 64 KB data and 32 KB instruction
Level 2 Cache
The 44P Model 170 processor card has either 1 MB (333 MHz) or 4 MB
(400 MHz) of L2 cache located on the processor card. L2 cache is used to lower the time spent accessing memory data and increase performance. The L2 cache extends L1 cache benefits by adding more cache to the memory pipeline.
The speed of the L2 cache is dependent upon the processor speed. The L2 cache speed for the 333 MHz processor is 167 MHz (2:1 ratio) and for the 400 MHz processor is 200 MHz (2:1 ratio).
The L2 cache uses a direct mapped cache methodology. There is a dedicated external interface to the L2 cache not shared with the 6XX bus. This allows concurrent access to both the L2 cache and the 6XX bus.
