18 SPE Mapper Functional Description
18.13.1 Pointer Interpretation Block
The TUG-3 pointer interpreter logic block performs all necessary functions to support TU-3 pointer interpretation.
The following features are implemented:
The SPE mapper includes event or change of state indicators for pointer interpreter states except the NORM state.
States NDF, DEC, and INC are reported with event status bits SPE_RNDFE (
SPE_RDECE
change of state (delta) status bits SPE_RAISD
for each event or delta state may be masked with bits SPE_RNDFM, SPE_RDECM, SPE_RINCM, SPE_RAISM,
and SPE_RLOPM (all in
Agere Systems Inc.
— LOP-TU3—loss of pointer
— AIS-TU3—TUG-3-AIS (all ones in H1 and H2)
— NDF—NDF enabled (1001, 0001, 1101, 1011, 1000)
— NORM—normal (disabled NDF, normal pointer)
— INC—increment (inverted I bits)
— DEC—decrement (inverted D bits)
The pointer interpreter consists of the following states:
