| | SIMD datapath coupled to scalar/vector/address/conditional data register file with selective subpath scalar processing ... |
 | | The preferred slot could be any of the functional units, by either defining them as preferred slot, or by means of dynamically determining a preferred slot, either by setting a control register, specifying a slot in the instruction word, or by determining it using any other means, e.g., by the issue unit at issue time. |
 | | Selected functional units can be enabled or disabled in accordance with the invention by enabling or disabling the clock input for the functional unit, or, in an alternative embodiment, by disabling the power input for the functional unit. |
 | | The ETL unit generates an enabling output which is used to enable or disable the clock (or power input) signal for the associated functional units, depending on whether they will be utilized to process the current instruction. |
