When the variable we want to manipulate is … WebLike Geier said, processors can't directly handle values smaller than a byte. So a boolean type that was actually implemented as just a single bit would in most cases be inefficient. The processor needs to do a bit of extra work to extract just that one bit. The reason that the boolean type exists is more about semantics than anything else.

WebDec 10, 2024 · The side-band ECC scheme is typically implemented in applications using standard DDR memories (such as DDR4 and DDR5). As the name illustrates, the ECC code is sent as side-band data along with the actual data to memory. For instance, for a 64-bit data width, 8 additional bits are used for ECC storage. Hence, the DDR4 ECC DIMMs, …

WebThe first concern is this makes for a much larger bus if adding side-band memory. Second, the codes are typically 7 or 8 bits, which makes for an inefficient use of a 16-bit memory structure.
