DESCRIPTION
The SY10/100E193 are error detection and correction (EDAC) circuits designed for use in new, high- performance ECL systems. The E193 generates hamming parity codes on an 8-bit word as shown in the block diagram. The P5 output gives the parity of the whole word. PGEN provides word parity after Odd/Even parity control and gating with the BPAR input. PGEN also feeds into a 1-bit shiftable register for use as part of a scan ring.
