The 68000 has a 16-bit external data bus so must transfer 32 bits of data in two consecutive steps, a technique called multiplexing: all this is transparent to the software, which was 32-bit from the beginning.

The 8080's large 40-pin DIP packaging permitted it to provide a 16-bit address bus and an 8-bit data bus, allowing easy access to 64 kilobytes of memory.

It had an 8-bit external data bus instead of the 16-bit bus of the 8086.

# Integer word-Signed 16-bit data.

# Unsigned Integer Word-Unsigned 16-bit data. Range from 0 to 65, 535.

In 1988, Intel introduced the i386SX, a low cost version of the 80386 with a 16-bit data bus.

INTERCAL-72 ( the original version of INTERCAL ) had only four data types, the 16-bit integer ( represented with a, called a ' spot '), the 32-bit integer (, a ' twospot '), the array of 16-bit integers (, a ' tail '), and the array of 32-bit integers (, a ' hybrid ').

( More modern versions of INTERCAL have by and large kept the same data structures, with appropriate modifications ; TriINTERCAL, which modifies the radix with which numbers are represented, can use a 10-trit type rather than a 16-bit type ), and CLC-INTERCAL implements many of its own data structures, such as ' classes and lectures ', by making the basic data types store more information rather than adding new types.

It was based on the Intel 8086 and, like it, had a 16-bit external data bus multiplexed with a 20-bit address bus.

The IBM System / 360 has a 32-bit architecture with 16 general-purpose registers, but most of the System / 360 implementations actually use hardware that implemented a much simpler underlying microarchitecture ; for example, the System / 360 Model 30 had 8-bit data paths to the arithmetic logic unit ( ALU ) and main memory and implemented the general-purpose registers in a special unit of higher-speed core memory, and the System / 360 Model 40 had 8-bit data paths to the ALU and 16-bit data paths to main memory and also implemented the general-purpose registers in a special unit of higher-speed core memory.

This chip resembled the 68HC000 in most respects, but its data bus could operate in either 16-bit or 8-bit mode, depending on the value of an input pin at reset.

The 68EC000 can have either a 8-bit or 16-bit data bus, switchable at reset.

The 6800 has a 16-bit address bus that could directly access 64 KB of memory and an 8-bit bi-directional data bus.

The 68020 had 32-bit internal and external data and address buses, compared to the early models with 16-bit data and 23-bit address busses.

The Neo Geo was marketed as 24-bit, though it was technically a parallel processing 32-bit system with 24-bit addressing and a 16-bit data bus with an 8-bit Zilog Z80 as coprocessor.

The new instructions work on new data types: 64-bit packed vectors of either eight 8-bit integers, four 16-bit integers, two 32-bit integers, or one 64-bit integer.

There are some inconsistencies in the WAV format: for example, 8-bit data is unsigned while 16-bit data is signed, and many chunks duplicate information found in other chunks.

The " ST " officially stands for " Sixteen / Thirty-two ", which referred to the Motorola 68000's 16-bit external bus and 32-bit internals.

MCA included numerous enhancements over the 16-bit AT bus, including bus mastering, burst mode, software configurable resources, and 32-bit capabilities.

( The Industry Standard Architecture, or " ISA ", name replaced the " AT " name commonly used for the 16-bit bus.

The newer 16-bit standard, the IBM AT bus, was introduced in 1984.

IBM designed the 8-bit version as a buffered interface to the external bus of the Intel 8088 ( 16 / 8 bit ) CPU used in the original IBM PC and PC / XT, and the 16-bit version as an upgrade for the external bus of the Intel 80286 CPU used in the IBM AT.

The 8-bit bus ran at 4. 77 MHz ( the clock speed of the IBM PC and IBM PC / XT's 8088 CPU ), while the 16-bit bus operated at 6 or 8 MHz ( because the 80286 CPUs in IBM PC / AT computers ran at 6 MHz in early models and 8 MHz in later models.

) IBM RT / PC also used the 16-bit bus.

I / O addressing could also sometimes employ the fact that the processor would output the same 8-bit port address to both the lower and the higher address byte ( i. e. IN 05h would put the address 0505h on the 16-bit address bus ).

The CPU remained fully 32-bit internally, but the 16-bit bus was intended to simplify circuit board layout and reduce total cost.

The 16-bit bus simplified designs but hampered performance.

Introduced in 1979 with HMOS technology as the first member of the successful 32-bit m68k family of microprocessors, it is generally software forward compatible with the rest of the line despite being limited to a 16-bit wide external bus.

Finally the SuperNOVA also replaced the earlier model ’ s 4-bits-at-a-time math unit with a new 16-bit parallel version, speeding math by up to four times.

* Half, also called float16, a 16-bit floating point value.

Still, much of the system had 16-bit code internally which required, among other things, device drivers to be 16-bit code also.

* There are two additional 8-bit accumulators, E and F. These can be concatenated to form a 16-bit accumulator called W. The existing 6809 16-bit accumulator, D, can also be concatenated with W to form a 32-bit accumulator Q.

The Intel 80286 ( also called iAPX 286 ), introduced on 1 February 1982, was a 16-bit x86 microprocessor with 134, 000 transistors.

Some instructions also enabled HL to be used as a ( limited ) 16-bit accumulator, and a pseudoregister, M, could be used almost anywhere that any other register could be used and referred to the memory address pointed to by HL.

It also had a 16-bit stack pointer to memory ( replacing the 8008's internal stack ), and a 16-bit program counter.

Although the 8080 was generally an 8-bit processor, it also had limited abilities to perform 16-bit operations: Any of the three 16-bit register pairs ( BC, DE, HL ) or SP could be loaded with an immediate 16-bit value ( using LXI ), incremented or decremented ( using INX and DCX ), or added to HL ( using DAD ).

The 8086 ( also called iAPX 86 ) is a 16-bit microprocessor chip designed by Intel between early 1976 and mid-1978, when it was released.

It had an extended instruction set that was source-( not binary -) compatible with the 8008 and also included some 16-bit instructions to make programming easier.

A range of 16-bit instructions treat the A and B registers as a combined 16-bit D register for comparison ( X and Y registers may also be compared to 16-bit memory operands ), addition, subtraction and shift operations, or can add the B accumulator to the X or Y index registers.

But then they expanded the line greatly with the introduction of the 65816, a fairly straightforward 16-bit upgrade of the original 65C02 that could also run in 8-bit mode for compatibility.

It can also apply a 16-bit repeating pattern to the line.

The 8086 was introduced during 1978 as a fully 16-bit extension of Intel's 8-bit based 8080 microprocessor and also introduced memory segmentation to overcome the 16-bit addressing barrier of such designs.
