TSS901E
The IEEE Std 1355-1995 specifies low level checks as link disconnect detection and parity
check at token level. The TSS901E provides, through the Protocol Processing Unit, features to
reset a link or all links inside the TSS901E, to reset the local CPU or to send special signals to
the CPU commanded via the links.
Additionally it is possible to enable a checksum coder/decoder to have fault detection capabili-
ties at packet level.
The TSS901E is a very high speed, scalable link-interface chip with fault tolerance features. The
initial exploitation is for use in multi-processor systems where the standardisation or the high
speed of the links is an important issue and where reliability is a requirement. Further application
examples are heterogeneous systems or modules without any communication features as spe-
cial image compression chips, certain signal processors (TSC21020F, ERC32, ...), application
specific programmable logic or mass memory.
The TSS901E could also be used for single board systems where standardised high speed
interfaces are needed. Even "non-intelligent" modules such as A/D-converter or sensor inter-
faces can be assembled with the TSS901E because of the "control by link" feature. The
complete control of the TSS901E can be done via link from a central controller-node.
