Dolphin ECC MCA Functional

This functional specification document details the design and operation of the ECC MCA chip intended for the Dolphin system. The chip is designed to provide single error correcting and double error detecting (SEC/DED) capabilities using a Hamming code on 36-bit data words. Key aspects covered include: - Operating Modes: Generation and checking modes for parity and ECC. - Design Goals: Efficient SEC/DED implementation, syndrome-based error location, and support for bit-sliced architectures. - Code Assignment: The specific Hamming code layout and mapping strategies, including re-mapping for 4, 6, and 8-bit slices. - Diagnostic Functions: Control via the Diagnostic Status Register, including various slice modes and error detection configurations. - Pin Assignments: Definitions for the functional pins of the ECC MCA.
