EC000 CORE PROCESSOR USER’S MANUAL
MOTOROLA
bus allows direct addressing of up to 4 Gbytes. Logic can be added to implement dynamic
bus sizing.
The SCM68000 is upward code compatible with all other members of the M68000 micropro-
cessor family. Any user-mode programs using the SCM68000 instruction set will run
unchanged on any MC680x0, MC68EC0x0, or MC683xx processor. This is possible
because the user programming model is identical for all processors and the instruction sets,
addressing modes, and data types for the SCM68000 are proper subsets of the complete
architecture.
The SCM68000 also includes some functions not found on the standard MC68000 and
MC68EC000 microprocessors such as the processor status, pipeline refill, and interrupt
pending signals. These signals permit emulation support and facilitate interfacing between
the SCM68000 and on-chip logic.
1.1 FLEXCORE INTEGRATED PROCESSORS
FlexCore allows designers of high-volume digital systems and third-party technology provid-
ers to place their proprietary circuitry on chip with a Motorola microprocessor. By using Flex-
Core, a designer can reduce the total system cost, component count, and power
consumption while providing higher performance and greater reliability. Up to 100,000 gates
or more of custom logic, memory, and peripheral modules can be added to a core processor
to produce the most cost-effective solution for a designer's system. The core processors
provide special power-management features such as 5 V, 3.3 V, and static operation. The
68000 Family of core processors offers the designer a range of performance from 3 to 12
million instructions per second (MIPS) (to be extended to 100 MIPS) while maintaining com-
plete code compatibility throughout the Family. The 68000 processors have a proven archi-
tecture with a broad base of application and system software support, including real-time
kernels, operating systems, and compilers, in addition to a wide range of tools to support
software development. In the future, additional processing architectures will be included in
the FlexCore program, including PowerPC
and digital signal processing (DSP). Figure 1-
1 shows a typical die layout for a FlexCore integrated processor.
Complete product lines can be created using FlexCore by implementing one base design
using a variety of core processors. Designers already familiar with 68000 Family design can
easily migrate to FlexCore processors as the core processors use the same bus interfaces
found on the standard 68000 Family members. Additionally, many peripheral modules and
memory elements are available for integration. Motorola has developed a complete design
system to put into the hands of the customer that includes both a broad cell-based library
and effective computer-aided design (CAD) tools. By building on Motorola's proven 68000
microprocessor architecture and superior manufacturing capabilities, FlexCore offers
designers the best path to higher system integration.
