There are two sections of cache memory in the core.
Unlike the older Z280 and Z380 it does not have (or need) a cache memory.
With this machine, Compaq uses a technique called cache memory.
A typical example would be a processor+memory 3D stack, with the cache memory stacked on top of the processor.
This is because a modern processor will usually try to keep blocks of code in its cache memory.
While data is being moved, a copy is saved in the cache memory.
In addition, the 68040 will have a large cache memory, which is a temporary storage of data.
To further complicate the issue, some systems have up to three levels of cache memory, with varying effective speeds.
Because cache memory is on the chip, any subsequent requests are executed quickly.
Users outside computer science usually call this cache virtual memory.
