GENERAL DESCRIPTION
The Z380
鈩?/div>
Microprocessor is an integrated high-
performance microprocessor with fast and efficient through-
put and increased memory addressing capabilities. The
Z380
鈩?/div>
offers a continuing growth path for present Z80-or
Z180-based designs, while maintaining Z80
廬
CPU and
Z180
廬
MPU object-code compatibility. The Z380
鈩?/div>
MPU
enhancements include an improved 280 CPU, expanded
4-Gbyte space and flexible bus interface timing.
An enhanced version of the Z80 CPU is key to the Z380
MPU. The basic addressing modes of the Z80 micropro-
cessor have been augmented as follows: Stack Pointer
Relative loads and stores, 16-bit and 24-bit indexed off-
sets, and more flexible Indirect Register addressing, with
all of the addressing modes allowing access to the entire
32-bit address space. Additions made to the instruction
set, include a full complement of 16-bit arithmetic and
logical operations, 16-bit I/O operations, multiply and
divide, plus a complete set of register-to-register loads
and exchanges.
The expanded basic register file of the Z80 MPU micropro-
cessor includes alternate register versions of the IX and IY
registers. There are four sets of this basic Z80 micropro-
cessor register file present in the Z380 MPU, along with the
necessary resources to manage switching between the
different register sets. All of the register-pairs and index
registers in the basic Z80 microprocessor register file are
expanded to 32 bits.
