description A software update architecture, system, apparatus, and methodology are provided for performing block-based swapping of OTA software stored as a plurality of compressed blocks in a first, smaller NVM with the system software stored as a plurality of decompressed blocks in a second, larger NVM by using a first decompressor circuit and first scratch memory to sequentially decompress each compressed code block of OTA software for storage in decompressed form as updated system software in the second, larger NVM while using a first compressor circuit and second scratch memory to sequentially compress each decompressed code block of system software for storage in compressed form as backup system software in the first, smaller NVM.
