KG11-A Exclusive-OR and CRC Block Check Option
The KG11-A Exclusive-OR and CRC Block Check Option is a UNIBUS co-processor which can calculate a number of different CRCs for use in data communication links. Data is transferred to and from the KG11 using programmed I/O.
The CRC computations it supports are:
- LRC-8 = X8 + 1
- LRC-16 = X16 + 1
- CRC-16 = X16 + X15 + X2 + 1
- CRC-12 = X12 + X11 + X3 + X2 + X + 1
- CRC-CCITT = X16 + X12 + X5 + 1
The KG11 is a single quad card.
