32-BIT FLOW-THRU ERROR DETECTION AND CORRECTION UNIT
COMMERCIAL TEMPERATURE RANGE
32-BIT DATA WORD CONFIGURATION
A single IDT49C465 EDC unit, connected as shown below, provides
all the logic needed for single-bit error correction, and double-bit error
detection, of a 32-bit data field. The identification code (00) indicates
seven checkbits are required. the CBI7 pin should be tied high.
The 39-bit data format for bytes of data and seven checkbits is
indicated below.
Syndrome bits are generated by an exclusive-OR of the generated
checkbits with the checkbits read from memory. For example, Sn is the
XOR of checkbits from those read with those generated. During Data
Correction, the syndrome bits are used to complement (correct) single-
bit errors in the data bits.
