Bit-serial architecture 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 a higher total performance than
Parallel port later than Windows 95/98 prevent user programs from directly writing to or reading from the LPT without additional software (kernel extensions). Current CNC Milling Machines also often make use of the parallel port to directly control the machine's motors and attachments. Traditionally IBM PC systems have allocated their first three parallel ports according to the configuration in the table below (if all three printer ports exist). If there is an unused slot, the port addresses of the others are moved up. (For example, if a port at 0x3BC does not exist, the port at 0x378 will then become the first
