-
4-Bit Parity OK Checker with XOR reduction, syndrome-based single-bit error correction, and sticky error flag.
-
Generates even parity for 8-bit data and latches a sticky error flag for odd parity occurrences.
-
An 8-bit parity error counter that accumulates odd parity errors in data streams. It supports scrubbing with external data and direct accumulator loading for testing.
-
Combinational even/odd parity generator using explicit even-parity XOR and mode mux.
-
SECDED byte-strobe parity scrubber for 32-bit data with SBE/MBE detection.
-
Hamming(16,11) single-bit error correction module for 16-bit buses with syndrome-based detection and registered output.
-
Glitch-free registered Hamming distance calculator for 8-bit vectors using $countones.
-
8-bit parity checker with selectable odd/even mode, LSB correction, and sticky error flag.
-
8-bit parity checker with sticky error flag and syndrome-based single-bit correction using data[2:0] as index.
-
8-bit parity checker with invert-select control and sticky error detection for single-bit error assumption.
-
An 8-bit register with 2-bit parity syndrome for single-bit error correction and detection.
-
Single Error Correction Double Error Detection Hamming check for 13-bit codewords.
-
Toy SECDED syndrome calculator for 4-bit nibbles with invalidate and shadow commit support.
-
Sticky Parity Error Flag 8-Bit — L1 Upgrade
-
Balanced XOR-reduction tree computing even parity for a 16-bit input vector.
