216COl

The Z16COl/CO2 CPU are members of the 16-bit The processor's resources include seven data types that processor and controller family. Designed using a range from bits to 32-bit long words, and byte and word RISC-like Load/Store architecture, the CPU can operate in strings, plus eight user-selectable addressing modes. The either system or normal modes, permitting privileged nine basic instruction types can be combined with various operations and improving operating system organization data types and addressing modes to form a powerful set and implementation. of 414 instructions.

To boost the main CPU's performance capability, the processor core includes hardwired control and is a 16-bit real-time processor functioning at register access speeds. Register flexibility is created by grouping or overlapping multiple registers, and by allowing extended register file capabilities as the system expands. Easy extended register file control is accomplished through a single instruction stream communication.

TheCPUsupportsthreetypesof interrupts (non-maskable, vectored, and non-vectored) and four traps (system call, extended process architecture instruction, privileged instructions, and segmentation trap). The vectored and non-vectored interrupts are maskable.

The extended processing architecture features provide a modular approach to expanding both the hardware and software capabilities of the Z16COl/CO2.
