From one VLOOP to the next VLOOP, the following state information is retained:
- Parameter pointer, advanced by parameter length in the first VLOOP
- Vector register contents, whatever left over from the last iteration of the first VLOOP
The following state information is not retained, thus must be configured within each VLOOP:
- Parameter register file (must be reloaded from data memory)
- Agen configuration, such as association of the four counts to parameter registers
- Agen address counter (reset at the beginning of each VLOOP execution)
