CHAPTER 3 CPU
3.1
Memory Space
The memory space of the F
data. Part of the memory space is used for specific uses such as the expansion
intelligent I/O service (EI
tables.
I Memory Space
I/O, programs and data are all allocated somewhere in the 16-MB memory space of the F
And the CPU can indicate their addresses in the 24-bit address bus to access each resource.
Figure 3.1-1 shows an example of the relationships between the F
