Patil Systems, Inc., was founded in Salt Lake City, Utah, in 1981 by Suhas Patil, and in 1983 the company was reorganized by Patil, Kamran Elahian, and venture capitalist Fred Nazem, whose firm, Nazem and Company provided the company's first/start-up round of financing. Later the company was renamed as Cirrus Logic when it moved to Silicon Valley in 1984 to focus on solutions for the growing PC components market. Michael Hackworth was named president and chief executive officer in January 1985, and served as CEO until February 1999. It joined the Nasdaq market listing in 1989 (symbol: CRUS). Cirrus Logic acquired Crystal Semiconductor, a supplier of analog and mixed-signal converter ICs, in 1991. In the early 1990s, Cirrus Logic became a supplier of PC graphics chips, audio converters and chips for magnetic storage products. David D. French joined Cirrus Logic, Inc. as president and chief operating officer in June 1998 and was named chief executive officer in February 1999. Soon after joining the company, through an acquisition strategy French repositioned the company into a premier supplier of high-performance analog and digital processing chip solutions for consumer entertainment electronics, and soon afterwards, M. Yousuf Palla joined as Vice President of Operations and Manufacturing, contributing further to its success. The company announced in April 2000 that it had completed moving its headquarters to Austin, Texas.[7] In June 2005, Cirrus Logic sold its video products operation to an investment firm, creating privately owned Magnum Semiconductor. After French resigned in March 2007, Jason Rhode, formerly the vice president and general manager of Cirrus Logic's Mixed Signal Audio Division, was named president and CEO in May 2007. In 2014 Cirrus Logic bought Wolfson Microelectronics for approximately $467 million. In 2021, Cirrus Logic acquired Lion Semiconductor for $335 million.[8] It had a robotics partnership with the Ann Richards School, in which Cirrus Logic committed $10,000 a year for three years. In 2023 the robotics team was made up of 10 girls, which increased to 30 in 2024.[9]

Graphics history

[edit]

In the early 1990s, Cirrus Logic was a supplier of low-cost PC graphics chips. Cirrus's Microsoft Windows 2D GUI accelerators (GDI) were among the fastest in the low-end market-segment, outperforming competing VGA chips from Oak Technologies, Trident Microsystems, and Paradise (Western Digital).[citation needed] For example, the Cirrus GD5422 (1992) supported hardware acceleration for both 8-bit color and 16-bit color. It was one of the lowest-priced SVGA controllers to support both.

By the mid-1990s, when PCs had migrated to the PCI bus, Cirrus had fallen behind S3 and Trident Microsystems. When the announced release date of the GD5470 "Mondello" came and went, Cirrus's reputation in desktop PC-graphics suffered.[citation needed] Mondello development took a back seat to the GD5464 which was near completion and proved to be a much faster design with the use of Rambus. (Because of this Mondello never got off the ground.)

The company's final graphics chips, the GD546x "Laguna" series of PCI/AGP 3D-accelerators, were novel in that they were one of the few video cards to use Rambus RDRAM. The patented use of tiled memory by the GD546x chips is still used by nearly all graphics processors today. However, like many other 2D and 3D chips at the time were gate limited by the process technology available at the time, the feature set of perspective-correct texture mapping, bilinear filtering, single-pass lighting, gouraud shading, and alpha blending, was incomplete compared to the next generation of 3D chips. The GD546x family was limited by CPU processing at the time, CPUs could not feed it enough triangles which was the real performance block. The raw processing power of the GD546x was nearly 2.5 million 25 pixel triangles per second, much faster than competitors.

When Intel announced they were entering the 3D market with the i740, Cirrus Logic exited the market, which at the time for Cirrus Logic was worth 500 million dollars annually. (Intel didn't catch up in performance for many years, the i740 was not widely accepted and did not win any major designs).

Cirrus Logic graphic cards are used in emulators. Both QEMU and Bochs emulate the Cirrus CLGD 5446 PCI VGA-card, with Bochs additionally emulating the CL-GD5430 ISA card.[citation needed]

History

Founding and Early Development

Cirrus Logic traces its origins to 1981, when established Patil Systems Inc. in , , with an initial focus on developing design automation tools for and systems-on-chip applications, drawing from Patil's research in silicon compilers and clockless circuit methodologies. The company began by creating microchip-level software and early prototypes, including a chip for that entered field trials with 20,000 units by 1983. This foundational work positioned Patil Systems at the intersection of software tools and hardware design, aiming to streamline complex development processes. In 1984, the company reincorporated as Cirrus Logic Inc. and relocated its headquarters to , in , to better access and talent in the burgeoning . This move marked a strategic shift toward full-scale semiconductor design and fabrication, with early successes in mixed-signal integrated circuits (ICs), such as a controller chip that achieved rapid market adoption. By the late 1980s, Cirrus Logic expanded into graphics controllers, releasing its first (VGA) controller chips in 1987–1989, which provided enhanced compatibility and performance for emerging PC displays, including flat-panel LCD variants. These innovations, including the CL-GD410/420 developed in partnership with Video Seven, helped establish the company as a key player in PC component solutions.
