Hyperstone, a fabless semiconductor and microprocessor design company, was founded in 1990 and is based in Konstanz, Germany. Together with subsidiaries in Taiwan, USA and with other worldwide partners, Hyperstone serves a global customer base.
Since July 2003, Hyperstone has been a member of the CML Microsystems Plc group. Traded at the London Stock Exchange, the group currently consists of eight subsidiaries and has over 250 employees. Hyperstone research and development is based in Germany and Taiwan. Industry-leading partners provide world-class wafer subcontracting, packaging, and testing services. Hyperstone’s success is based on the unique design of the unified RISC/DSP processor architecture. This core architecture provides both a fast RISC processor for data and control functions together with a powerful DSP unit for efficient algorithm execution. Hyperstone designs’ require less silicon, are more power efficient and require lower software complexity when compared to conventional dual-core designs.
Until today Hyperstone delivered over 55 million microcontrollers into fast growing markets, especially Flash Memory Cards. Additionally and as of today, Hyperstone's RISC / DSP processor core can be found as the heart of over 20 million digital still cameras.

Developments that have relevant meaning for the world market of processor technology also come from Germany. Since the founding of Hyperstone in Constance, on Lake of Constance - and it's not only us who find that remarkable.

We have worked successfully with Infineon for many years and have been very happy to do so. Around the world, we are appreciated as one of the very few developers of high complexity processor technology. This may well have something to do with our corporate history, which says one thing above all: even though strange words mark our everyday work - the words "stand still" are absolutely foreign to us

In the early days of the company, the 32-bit RISC architecture was created by CPU pioneer Dr. Otto Mueller, who had been developing office computers at Nixdorf before the world knew what PC was.

Joint and full integration of RISC and DSP on one processor core foor the first time: This development was met with great interest even from the international "Microprocessor Report". Ten years later, in 2006, the "E1" processor is used in more than 50 million applications worldwide.

Market launch of the "F1" processor: By 2006, this controller (F1, later F2, and later F3) was in use in more than 15 million flash memory solutions worldwide.

First Publications on the topics "System on single chip" and hyNet® XS.

Hyperstone demonstrated the capabilities of the hyNet® XS with the very first examples, the so-called "first silicon".

Development of USB flash drive U2 with interface for SD / MMC. The U2 ist ehe world's first single-chip "combo-controller".

With the hyNet® S, Hyperstone brings a second version of the highly integrated network controller to market. This offers a comination of Ethernet interfaces, hub functionality and PCI interface for the first time, as well as further features and interfaces on a single chip. Further derivatives followed in 2006. All hyNet® processors support the future real-time Ethernet standards "Ethernet Powerlink", "PROFINET" and "EtherNet/IP".

Development of F3 Flash Memory Controller for CF and Solid State Disk and S6 Flash Memory Controller for SD card applications.

Development of F4, S7 and S8 Flash Memory Controller for Flash Card Applications and A1 Flash Memory Controller for Solid State Disk.
