The integer units are 64-bit, but the FPU was single-precision, or 32-bit.

The custom instruction set was implemented by grouping the two 64-bit integer units.

That said, as incremental improvements go, adding a whole separate set of four integer units is a pretty large increment.

The second integer unit was not identical to the first, and was only capable of executing simple but more frequently used instructions.

The integer units have no multiply capability, instead using the floating point pipe for those operations.

The integer unit is responsible for executing integer instructions.

The example assumes each queue currently has only 3 commodities: red, green, and blue, and these are measured in integer units of packets.

Major improvements were improved superscalar execution and an extra integer unit.

The integer unit had 32, 64-bit-wide registers.

All models had 4.3 million transistors, with five integer units that could process instructions out of order and one floating point unit.
