Motorola

Motorola, Inc.

Motorola, Inc.

<company> One of the world's leading providers of wireless communications, semiconductors and advanced electronic systems and services. Major equipment businesses include cellular telephone, two-way radio, paging and data communications, personal communications, automotive, defense and space electronics, computers, satellite communications systems, police and emergency service radio systems, taxicab dispatching (radio) systems. Communication devices, computers and millions of consumer products are powered by Motorola semiconductors. They are probably best known in the computing world for their microprocessors, including the Motorola 6800 and {Motorola 68000} CISC families and Motorola 88000 RISCs, the Motorola DSP56000 digital signal processors and the PowerPC on which they collaborated. They also led the development of VMEbus. Quarterly sales $5400M, profits $367M (Aug 1994). See also Envoy, Monsoon, MPL. http://mot.com/. Address: Schaumberg, Illinois, USA. (1994-12-01)

<processor> (MC68000) The first member of Motorola, Inc.'s family of 16- and 32-bit microprocessors. The successor to the Motorola 6809 and followed by the Motorola 68010. The 68000 has 32-bit registers but only a 16-bit ALU and external data bus. It has 24-bit addressing and a {linear address space}, with none of the evil segment registers of Intel's contemporary processors that make programming them unpleasant. That means that a single directly accessed array or structure can be larger than 64KB in size. Addresses are computed as 32 bit, but the top 8 bits are cut to fit the address bus into a 64-pin package (address and data share a bus in the 40 pin packages of the 8086 and {Zilog Z8000}). The 68000 has sixteen 32-bit registers, split into data and address registers. One address register is reserved for the Stack Pointer. Any register, of either type, can be used for any function except direct addressing. Only address registers can be used as the source of an address, but data registers can provide the offset from an address. Like the Zilog Z8000, the 68000 features a supervisor and user mode, each with its own Stack Pointer. The {Zilog Z8000} and 68000 are similar in capabilities, but the 68000 is 32 bits internally, making it faster and eliminating forced segmentations. Like many other CPUs of its generation, it can fetch the next instruction during execution (2 stage pipeline). The 68000 was used in many workstations, notably early Sun-2 machines, and personal computers, notably {Apple Computer}'s first Macintoshes and the Amiga. It was also used in most of Sega's early arcade machines, and in the Genesis/Megadrive consoles. Variants of the 68000 include the 68HC000 (a low-power HCMOS implementation) and the 68008 (an eight-bit data bus version used in the Sinclair QL).

Motorola

Motorola, Inc. () was an American multinational telecommunications company based in Schaumburg, Illinois. It was founded in 1928 as Galvin Manufacturing Corporation by brothers Paul and Joseph Galvin. The company changed its name to Motorola in 1947. After having lost $4.3 billion from 2007 to 2009, the company split into two independent public companies, Motorola Mobility and Motorola Solutions, on January 4, 2011. The reorganization was structured with Motorola Solutions legally succeeding Motorola, Inc., and Motorola Mobility being spun off.

Motorola designed and sold wireless network equipment such as cellular transmission base stations and signal amplifiers. Motorola's home and broadcast network products included set-top boxes, digital video recorders, and network equipment used to enable video broadcasting, computer telephony, and high-definition television. Its business and government customers consisted mainly of wireless voice and broadband systems (used to build private networks), and, public safety communications systems like Astro and Dimetra. These businesses, except for set-top boxes and cable modems, became part of Motorola Solutions.

Motorola's wireless telephone handset division was a pioneer in cellular telephones. Also known as the Personal Communication Sector (PCS) prior to 2004, it pioneered the "mobile phone" with DynaTAC, "flip phone" with the MicroTAC as well as the "clam phone" with the StarTAC in the mid-1990s. It had staged a resurgence by the mid-2000s with the RAZR, but lost market share in the second half of that decade. Later it focused on smartphones using Google's open-source Android mobile operating system. The first phone to use Android 2.0 "Eclair", the Motorola Droid, was released in 2009 (the GSM version launched a month later, in Europe, as the Motorola Milestone). The handset division, along with the cable set-top box and modem businesses, were later spun off into Motorola Mobility.
