This Panel, like Panel D, is concerned with the floating point and fixed point arithmetic.
It gives more specific information related to the three independent Adders and two Multiply/Divide (M/D)
units. See Panel D for more information overall.
Each unit can run independently so there is a need for synchronising the activities so that the results appear correctly.
Source and sink tags provide this.
The SHORT PRECISION indicator shows that the operation being accomplished is of that precision.
Registers are used to hold the data required for the arithmetic units. Once the unit has taken the data, it is able to mount its next data
from the Common Data Bus (CDB).
To the bottom and left of the panel more indicators show the micro state of the multiply/divide unit that has a set of sub-cycle states
as it performs either a multiply or divide.
The middle area contains additional information on the state of the units. The adder units have two stages and
they can be processing two additions in the first and second cycle of the unit. Three reservation stations feed the adder units and
two feed the multiply/divide units. Once the data has been consumed by the arithmetic unit the reservation station can start loading the next piece of data required
in a subsequent operation.
The area to the right hand side is devoted to indicating the detailed state of the fixed point unit and its buffer registers.
