C68000 Megafunction Datasheet
Functional Description
The C68000 megafunction is partitioned into
modules as shown above and described below.
Execution Unit
Arithmetic-Logic Unit. (ALU) performs:
Address/Data Shifter performs various types of
shift and rotate operations by one bit position.
32-bit arithmetic operations
32-bit logic operations
Bit manipulations
These two units with some additional logic,
allows all basic operation on data and address
registers.
Program counter
The program counter (PC) is 32 bits wide. This
register can be incremented or loaded by the
control unit during instruction execution.
Interrupt control
Provides seven priority levels of interrupt and
calculates an internal vector during the auto-
vector interrupt. It also holds the internal state of
the interrupt and exception level.
Data registers
Contains eight 32-bit wide data registers (user
visible). There is also a temporary data register
that is invisible to the user.
Address registers
Contains eight 32-bit wide address registers (user
visible). There is also a temporary data register
that is invisible to the user.
Special registers
Contains the stack pointer, SR and additional
special purpose registers.
Main control
Decodes and executes instructions. Contains
main processor sequencer and control unit for all
inner resources.
Interface
Manages all accesses to memory. Generates all
control signals to memory and peripherals. This
is a synchronous device working with both rising
and falling edge of the clk(clock) signal.
Deliverables
VHDL or Verilog RTL
Post-synthesis EDIF netlist (netlist license)
Testbench (self checking)
Vectors for testing the megafunction
Place & Route Scripts (netlist license)
Synthesis and simulation scripts
Constraint file

Documentation
Verification Methods
The C68000 megafunction’s functionality was
verified by means of a proprietary hardware
modeler. The same stimulus was applied to a
hardware model that contained the original Motorola
MC68000 chip, and the results compared with the
megafunction’s simulation outputs
