Bit-serial architecture a single N-bit parallel processor. Bit-serial architecture In digital logic applications, bit-serial architectures send data one bit at a time, along a single wire, in contrast to bit-parallel word architectures, in which data values are sent all bits or a word at once along a group of wires. All computers before 1951, and most of the early massive parallel processing machines used a bit-serial architecture—they were serial computers. Bit-serial architectures were developed for digital signal processing in the 1960s through 1980s, including efficient structures for bit-serial multiplication and accumulation. Often N serial processors will take less FPGA area and have
Parallel Redundancy Protocol to as PRP-0 as it is still used in some control systems, and PRP 2012 as "PRP". An interesting application of PRP was found in the area of wireless communication as "Timing Combiner" [], yielding significant improvement in packet loss and timing behaviour over parallel redundant wireless links. Parallel Redundancy Protocol Parallel Redundancy Protocol (PRP) is a network protocol standard for Ethernet that provides seamless failover against failure of any network component. This redundancy is invisible to the application. PRP nodes have two ports and are attached to two separated networks of similar topology. PRP can be implemented entirely in
