quantities are, of course, those multiply and divide operations with 32-bit products or div-
idends.
Lastly, all word Input/Output operations are performed on 16-bit values.
Address Spaces
The Z380 CPU architecture supports five distinct address spaces corresponding to the dif-
ferent types of locations that can be accessed by the CPU. These five address spaces are:
CPU register space, CPU control register space, memory address space, and I/O address
space (on-chip and external).
CPU Register Space
The CPU register space is shown in Figure 33 and consists of all of the registers in the
CPU register file. These CPU registers are used for data and address manipulation, and are
an extension of the Z80 CPU register set, with four sets of this extended Z80 CPU register
set present in the Z380 CPU. Access to these registers is specified in the instruction, with
the active register set selected by bits in the Select Register (SR) in the CPU control regis-
ter space.
