	WDC 65816/65802 - Wikipedia, the free encyclopedia
		The WDC 65816 (also: 65C816), a 16-bit microprocessor CPU developed by the Western Design Center (WDC), is an expanded and compatible successor to the venerable MOS Technology 6502.
		The 65816 was second-sourced by GTE, Sanyo and a couple of other semiconductor companies from the mid-to-late 1980s to the early 1990s.
		The chip was designed as an upgrade path from the 8-bit 6502/65C02 to the new 65816 16-bit CPU.

		It was designed as a single chip version of the TI 990 minicomputer series, much like the Intersil 6100 was a single chip PDP-8, and the Fairchild 9440 and Data General mN601 were both one chip versions of Data General's Nova.
		Alpha was also designed for the future for a 1000-fold eventual increase in performance (10 X by clock rate, 10 X by superscalar execution, and 10 X by multiprocessing) Because of this, superscalar instructions may be reordered, and trap conditions are imprecise (like in the 88100).
		RISC designs call for each instruction to be a single, fixed length and to execute in a single cycle, which is done with pipelines, no microcode (to reduce chip complexity and increase speed).

		In addition to the actual microchips, WDC offers the chips' designs as IP cores to be used inside other chips (like ASICs), and provides ASIC and embedded systems consulting services revolving around their processor designs.

		It used the new Western Design Center 65816 16-bit microprocessor running at 2.8 MHz, which was faster than the 8-bit 6502 and 65C02 processors used in earlier Apple IIs and also allowed the II to use more RAM.
		The motherboard design was also designed to increase audio quality and allow more power to be delivered to cards in the expansion slots.
		Apple's first internal project to develop a next-generation Apple II based on the 65816 was known as the "IIx." The IIx project, though, became bogged down when it attempted to include various coprocessors allowing it to emulate other computer systems.

		Some of the designers left to start MOS Technologies (later bought by Commodore), which introduced the 650x series which included the 6501 (pin compatible with the 6800, taken off the market almost immediately for legal reasons) and the 6502 (used in early Commodores, Apples and Ataris).
		It is expected to be a VLIW design similar to the TI 320C6x DSP, and will be compatible with the 80x86 - it will include 80x86 data and segment registers, with additional instructions to switch between instruction/register sets and transfer data between 80x86 and IA-64 registers.
		The SH is also designed for the embedded marked, and is similar to the ARM architecture in many ways.

		Motorola 6809 was the original design choice, and some prototypes were built, but they quickly realised that it didn't have the power for a GUI based OS, and they used the Lisa's 68000, borrowing some of the Lisa low level functions (such as graphics toolkit routines) for the Macintosh.

		The design was also limited with no interrupt support, no stack or index registers (though the port addresses could function as such), and no subroutine support (the XEC instruction would execute an instruction without incremeting the PC, and could be used to implement subroutines).
		Most instructions are predicated, a design very similar to the TI 320C6x DSP, but with 128 general 64-bit and 128 floating point registers, and 64 predicate bits (a type of condition code).
