The i combined a number of features that were unique at the time, most notably its very long instruction word VLIW architecture and powerful support for high-speed floating point operations.

Intel referred to the design as the “i Bit Microprocessor”. The Road To Gold”. The system had separate pipelines for the ALU, l845gl point adder and multiplier, and could hand off up to three operations per clock. Mercury Computer Systems used the i in their multicomputer.

The entire i design was based on the compiler efficiently handling this task, which proved almost impossible in practice. Pixar produced a custom version of RenderMan to run on the card that ran approximately four times faster than the host.

For grapjics, an instruction to add two numbers will take considerably longer if the data are not in the cache, yet there is no way for the programmer to know if they are or not. Views Read Edit View history. It was released with considerable fanfare, slightly obscuring the earlier Intel iwhich was successful in some niches of embedded systemsand which many considered to be a better design.


All of the buses were at least 64 bits wide.

Both units had thirty-two bit registers, but the FPU used its set as sixteen bit registers. Andy Grove suggested that the i’s failure in the marketplace was due to Intel being stretched too thin:. So we introduced both, figuring we’d let the marketplace decide.

From 2 to compute nodes would reside in a circuit switched fat tree network, with each node having local memory that could be mapped by any other node. Not to be confused with Graphicz chipset.

Retrieved from ” https: One unusual feature of the i was that the pipelines into the functional units were program-accessible VLIWrequiring the compilers to order instructions carefully in the object code to keep the pipelines filled. Wikimedia Commons has media related to Intel i Truevision produced an ibased accelerator board intended for use with their Targa and Vista framebuffer cards. Intel i microprocessor 50 MHz edition. The i was an attempt to avoid this entirely by moving this duty off-chip into the compiler.

We now had two very powerful chips that we were introducing at just about the same time: On paper, performance was impressive for a single-chip solution; however, real-world performance was anything but. This sort of use slowly disappeared as well, as more graphicd CPUs started to match the i’s performance, and as Intel turned its focus to Pentium processors for general-purpose computing.

We didn’t know what to do. From Wikipedia, the free encyclopedia.

Confusingly, the number has since been re-used for a motherboard control chipset for Intel Xeon high-end Pentium systems and a model of the Core i7. The i did see some use in the workstation world as a graphics accelerator. Another serious problem was the lack of any solution to handle context switching graphiccs.
