Advanced Application Chipset

Article is work in progress.

Advanced Application Chipset (also known as the AA Chipset) is a RISC-based application-specific integrated circuit of chipsets developed by Omega Logic and introduce in the mid-1990s. Using VLIW as the core technology of the Advanced Application Chipset, it became a successful project for the company.

Designed for use in workstations, supercomputers and other devices, the AA Chipset took advantage of the VLIW core technology and RISC-based instructions.

History
In 1993, Omega Logic has teamed up to create a 600nm RISC-based application-specific integrated circuit chipset. During that time at the CES 1994 show, Omega Logic announced a 600nm RISC-based application-specific integrated circuit chipset called the "AA chipset".

The first batch of AA chipsets were manufactured on June 1995 at TSMC in Taiwan. Omega Logic became successful when the AA Chipset was released to the general public.

On September 1995, the first batch of the 350nm AA chipsets became available. On the same year, Omega Logic announced a second revision to the AA Chipset called "AA Duo", which was released released in 1996. It features performance improvements over the first revision.

In late-1997, the first 250 nanometer variants of the chipsets were produced and became available to the general public. Later, Omega Logic unveiled the following chipsets in the AA series, "AA Trio" and "AA+" (not to be confused with the cancelled Amiga chipset). The AA Trio includes a more powerful DSP and flexible SIMD operations, while the AA+ added features that aren't present on the original chipset.

In the early 2000, a 180nm version of the following chipsets were produced.

In 2003, a new chipset called "AA Quadro-MT" has been unveiled. Using multi-threading as the secondary core of the chipset, it has a succesful performance impact.

Technology
The AA Chipset was one of Omega Logic's first ever chipset to be produced. Using VLIW and RISC as the core technologies, it runs at a faster clock rate than most of the RISC processors/chipsets at that time.

C/C++ programs, audio and video streams are optimized using special methods, such as data/instruction pre-fetching.
