During this period, Myers also authored his first four books, including The Art of Software Testing, a book that became a classic and a best-seller in the computer science field, staying in print for 26 years before it was replaced by a second edition in 2004. Myers also served as a lecturer in computer science at the Polytechnic Institute of New York University, where he taught graduate-level courses in computer science. Years later, he was the 1988 recipient of the J.-D. Warnier Prize for his contributions to the field of software engineering

Intel 80386

The Intel 80386, also known as the i386, or just 386, was a 32-bit microprocessor introduced by Intel in 1985. The first versions had 275,000 transistors and were used as the central processing unit of many workstations and high-end personal computers of the time...

, a type of RISC vector-processing machine, and the RISC-oriented 80960 (i960). Myers also chaired Intel's Microprocessor Strategic Business Segment, part of Intel's strategic long-range planning process.

In 1983, Myers moved to Oregon to take personal charge of the design of the i960 microprocessor. The i960 was the first microprocessor chip that could execute multiple instructions in parallel. In 1986, Myers co-authored an invited paper with Intel senior vice presidents Albert Yu and Dave House that outlined Intel's microprocessor thinking for the next 10 years. In 1990, Myers, for his work on the i960 microprocessor, was one of three finalists for Discover Magazine's Awards for Technological Innovation

RadiSys

In 1987, Myers and key i960 chip manager Dave Budde left Intel and founded RadiSys Corporation. Myers took the roles of CEO and Chairman, positions he held until 2002. A number of other Intel employees quickly joined the new venture, all of whom worked for no salary and instead invested money in the startup (in trade for stock). Because 1987 turned out to be one of the worst periods in history for raising venture capital, the early employees moonlighted to keep RadiSys afloat; for instance, Myers returned to Intel as a consultant on the design of the Intel 80486

The Intel 80486 microprocessor was a higher performance follow up on the Intel 80386. Introduced in 1989, it was the first tightly pipelined x86 design as well as the first x86 chip to use more than a million transistors, due to a large on-chip cache and an integrated floating point unit...

 (IPO). The company then grew rapidly, in part because of a series of acquisitions, including a division of Intel, two small operations from IBM, and several other private companies.

In 2000, under Myers' leadership, RadiSys had revenues of $341 million, net income of $33 million, a market cap in excess of $1 billion, and 1153 employees. The company became increasingly focused on the telecommunications market, with Nokia being its largest customer and representing over 20% of its revenue. In 2002, after a series of disagreements with the board of directors, Myers left and formed IP Fabrics, and nine other key RadiSys managers and engineers quickly joined him there.

IP Fabrics

Myers, along with nine others who left RadiSys, founded IP Fabrics in 2002 and became its CEO. He raised $8 million in venture capital from Intel Capital, Ignition Partners, Northwest Venture Associates, and Frazier Technology Partners. Initially, IP Fabrics' business was providing a virtualization
