Hardware-Supported Software Features
Zilog’s eZ8 MCU, latest 8-bit MCU meets the continuing demand for
faster and more code-efficient microcontrollers. It executes a superset of
the original Z8
®
instruction set. The eZ8 MCU features include:
•
Direct register-to-register architecture allows each register to function
as an accumulator, improving execution time and decreasing the
required Program Memory.
•
Software stack allows greater depth in sub-routine calls and interrupts
more than hardware stacks.
•
Compatible with existing Z8 code.
•
Expanded internal Register File allows access up to 4 KB.
•
New instructions improve execution efficiency for code developed
using higher-level programming languages including C.
•
Pipelined instruction fetch and execution.
•
New instructions for improved performance including BIT, BSWAP,
BTJ, CPC, LDC, LDCI, LEA, MULT, and SRL.
•
New instructions support 12-bit linear addressing of the register file.
•
Up to 10 MIPS operation.
•
C-Compiler friendly.
•
2 to 9 clock cycles per instruction.
