Upper right Welcome to the end of our tour… the boring part — at least at the first look. They offer a high level of hardware features — no costs were feared. If you are in need of the drivers, I make them available here. Using the Bit bus on the DSM cards one can build quite a big parallel computer.

The i did see some use in the workstation world as a graphics accelerator. The entire i design was based on the compiler efficiently handling this task, which proved almost impossible in practice. IEEE floats or vectors of bytes and words are kept in 32 bit registers f0 through f31, which can also be configured as 16 x 64 i. It was essentially a bit integer unit using the FPU registers as eight bit registers.

The i had several pipelines for the ALU and FPU parts and an interrupt could spill them and require them all to be re-loaded. Instructions for the ALU exterjal fetched two at a time to use the full external bus. As mentioned above, the Host and the DSM-card are communicating through a memory-window of diffenrent sizes, depending on the DSM used.

AFAIK, they never offered an expansion for sale. Some still featuring labels, most of them peeling off. The system had separate pipelines for the ALU, floating point adder and multiplier, and could hand off up to three operations per clock.

The i never achieved commercial success and the project was terminated in the mids. Upper left This is the most modern part of the board as by standards. Some things worth to mention: This took 62 cycles i86 the best case, and almost cycles in the worst. Colored arrows show start and end of each wire. Looking closer, I spotted a difference. Program is running successfully! For the whole enchilada, get the Manual here. Sad enough, the APX is not included on the driver disks and was sold seperately… for a lot of money.

We need a bit of pin-1s leg so when cutting it, be sure to cut it as close to the board as possible! Intel i instructions acted on data sizes from 8-bit through bit.

I wish everything would be that well documented. And a wild mixture it is! Due to several performance problemsthe i never achieved commercial edternal and the project was abandoned in the mids. Truevision produced an ibased accelerator board intended for use with their Targa and Vista framebuffer cards.

Both are identical… if you happen to own a NumberSmasher with a different label, get the dumpfile here for comparison. It supported a number of commands for SIMD -like instructions in addition to basic bit integer math. After a long time, I had a look at my 3 NumberSmashers again.

The presentation held at Hot Chips Conference On the above picture you can clearly see e. On the main-card are 3 other jumpers: The price of the card was as hefty as their competitors:
