Motorola Microprocessors Power Apple Macintosh Computers

Quadra Systems Outperform 486-Based Machines By 30 Percent

AUSTIN, Texas, Oct. 21, 1991 -- PRNewswire -- The Microprocessor and Memory Technologies Group of Motorola, Inc. (NYSE: MOT) today announced that its 68040, 68030 amd 68000 microprocessors provide the processing power for Apple(R) Computer, Inc.'s new Macintosh(R) Quadra(tm) high performance personal computers, Macintosh Classic(R) II and Macintosh PowerBook(tm) notebook series.

"Motorola is extremely proud that Apple chose the 68000 as the CPU architecture for its Macintosh product family," said Jim Reinhart, manager, M68000 marketing and applications, Motorola, Inc. "We've shared in many of Apple's successes over the years, and we're honored to play a part in today's impressive product roll-out because the new products demonstrate how Apple and Motorola continue to provide the high performance, low-cost personal computer systems that users demand."

The Macintosh Quadra 700 and Quadra 900 systems are powered by Motorola's 25-MHz 68040 microprocessors which, combined with several new product features, make the systems perform significantly faster than previously available high performance systems from Apple.

The 68040 is the most advanced, highest throughput single-chip microprocessor on the market today. It features 1.2 million transistors and is capable of executing up to 22 million instructions per second (MIPS) and 3.5 million floating operations per second (MFLOPS) at 25-MHz.

Motorola's 68040 microprocessor running at 25-MHz achieves higher performance levels than Intel's 486 running at 33-MHz -- a 33 percent faster clock speed. The 68040's RISC-like design and advanced features, such as its dual memory systems, sophisticated memory controller and pipelined integer and floating point units, give it a significant performance advantage over the 486. The 68040 at 25-MHz is faster in all aspects of performance than Intel's 486 at 25-MHz, achieving 22 MIPS compared to 15 MIPS.

The 68040 outperforms both complex and reduced instruction set computing (CISC and RISC) microprocessors. Fabricated with Motorola's 0.8-micron high-performance complementary metal-oxide semiconductor (HCMOS) process, the 68040 combines an integer unit, a floating point unit, two memory-management units, and two 4-kilobyte cache memories -- one for data and one for instructions.

The 68040 delivers up to four times the performance of the 68030, while remaining binary software compatible with all other 68000 family members. This compatibility enables Motorola customers to take advantage of the family's $8 billion installed base of 32-bit software, and also simplifies hardware upgrades.

The Macintosh Classic II is powered by the Motorola 68030. The PowerBook 100 features a 16-MHz 68000 microprocessor, and model 140 features a 16-MHz 68030. The PowerBook 170 incorporates both a 25-MHz 68030 and 25-MHz 68882 microprocessors.

The 68000 is a general-purpose microprocessor featuring a 32-bit flexible register set, large linear address space, a powerful instruction set and flexible addressing modes. The 68030 also features a 32-bit register set plus performance of 12 MIPS, a 256-byte instruction set and data cache, a co-processor interface and on-chip MMU. The 68882 is an enhanced floating point coprocessor that serves as the math coprocessor for the 68030.

Motorola is one of the world's leading suppliers of electronic equipment, systems, components and services for worldwide markets. Products include two-way radios, pagers, cellular telephone systems, semiconductors, defense and aerospace electronics, automotive and industrial electronic equipment, computers, data communications and information processing and handling equipment.

Motorola was a winner of the first Malcolm Baldrige National Quality Award in recognition of its superior company-wide quality management process.
