  AMD 29000 - Wikipedia, the free encyclopedia
The AMD 29000, often simply 29k, was a popular family of RISC-based 32-bit microprocessors and microcontrollers from Advanced Micro Devices.
The majority of AMD's resources were then concentrated on their high-performance, desktop x86 clones, using many of the ideas and individual parts of the latest 29k to produce the AMD K5.
The first 29000 was released in 1988, including a built-in MMU but floating point support was offloaded to the 29027 FPU.

AMD 5K86-P90 (SSA/5) Microprocessor The K5 was developed by AMD to compete with Intels Pentium microprocessor range.
AMD K6-2 Microprocessor The K6-2 was a x86 microprocessor manufactured by AMD, available in speeds ranging from 266 to 550 MHz.
Turion 64 is AMDs 64-bit mobile processor, intended to compete with Intels Pentium M. It is compatible with AMDs Socket 754 and is equipped with 512 or 1024 KB of L2 cache, a 64-bit single channel on-die memory controller, and an 800MHz HyperTransport bus.

The AMD 29000 is another load-store CPU descended from the Berkeley RISC design (and the IBM 801 project), as a modern successor to the earlier 2900 bitslice series (see picture here) (beginning around 1981).
These features make the 29000 useful for embedded applications, which is where most of these processors are used, allowing it at one point to claim the title of 'the most popular RISC processor'.
AMD made an external FPU (actually an arithmetic accelerator) for the 29K but it was quickly superceded by the onboard FPU of the 29050.

Like the SPARC design that was introduced shortly afterward, the 29000 has a large register set split into local and global sets.
In addition, the 29000 allows variable sized windows allocated from the 128 register stack cache.
The 29000 also includes an MMU and support for the AMD 29027 FPU.

AMD positions the 29000 family for embedded systems ranging from laser printers, X-terminals, graphics, RAID (redundant array of inexpensive disks), telecommunications, and networking.
The 29000 is a difficult processor to classify because it has three product lines within the same family.
Intel and AMD have embedded PC chips, the i386EX and Am386EM, respectively, that combine a low-power static core with a full set of PC-class peripherals, such as an interrupt controller, DMA, timers, and serial I/O. AMD’s Am386SC integrates its 386 static core with a PC peripheral set for handheld applications.

 Great Microprocessors of the Past and Present
AMD also produced what is probably the first floating point "coprocessor" for microprocessors, the AMD 9511 "arithmetic circuit" (1979), which performed 32 bit (23 + 7 bit floating point) RPN-style operations (4 element stack) under CPU control - the 64-bit 9512 (1980) lacked the transcendental functions.
Like the Nx586, AMD K5, and Intel's "Pentium Pro", the the third stage of the 10-stage 68060 pipeline translates the 680x0 instructions to a decoded RISC-like form (stored in a 16 entry buffer in stage four), and uses resource renaming (with fourty rename registers) to reorder instructions.
The 960 was aimed for the high end embedded market (it included multiprocessor and debugging support, and strong interrupt/fault handling, but lacked MMU support), while the 860 was intended to be a general purpose processor (the name 80860 echoing the popular 8086).

 EDN Access -- 09.14.95 EDN's 22nd Annual µP/µC Directory - 32-bit chips
The 29000 (29K) is a difficult processor family to classify because the family comprises three product lines, including three-bus Harvard-architecture processors, two-bus processors, and µCs with on-chip peripheral support.
AMD's 386SC300 chip has four power-saving modes: low speed (CPU goes to 0.5 MHz); doze, which stops CPU, system, and DMA clocks; sleep, which stops additional clocks and peripherals; and suspend, which stops everything except RTC and memory.
AMD's K5, although software- and pin-compatible with Intel's Pentium, is a unique 586-class CPU.

AMD says the K5 is its first x86-compatible CPU family that discards all vestiges of Intel's intellectual property (including microcode) while delivering better-than-Intel performance.
AMD claims the K5's microarchitecture has enough performance headroom to compete with all the se processors, and that faster versions will soon follow.
Even though not even AMD would claim the K5 is a fault-tolerant processor, it's comforting to know there's a mechanism of last resort that is robust enough to handle a logic glitch and confused code.

That compromise is symbolic of AMD's long quest to challenge Intel's supremacy in microprocessors--a quest that has been dogged with legal obstructions and technical hurdles at every turn.
For years, AMD has lagged at least a full generation behind Intel in x86 evolution, relying heavily on licensed technology and minor variations of Intel chips to carve out a pittance of market share.
AMD CEO Jerry Sanders, visiting Austin for a quarterly strategy meeting in late 1993, declared that an independently designed fifth-generation x86 chip was AMD's top priority.

The superscalar 29050 version in 1990 integrated a redesigned FPU (4 instructions could be dispatched to execute out of order and speculatively).
In the future Hewlett-Packard plans to pursue a "post-VLIW" (Very Long Instruction Word) design in conjunction with Intel code named "Merced" or IA-64, possibly expanding on the idea of MAX or MMX operations.
Some of the newer CPUs which execute Intel 80x86 instructions (The AMD 'K5' and NexGen Nx586, for example) treat 80x86 instructions as VLIW instructions, decoding them into RISC-like instructions and executing several concurrently.

* AMD 29k support A new user controllable variable 'call_scratch_address' can specify the location of a scratch area to be used when GDB calls a function in the target.
This is necessary because the usual method of putting the scratch area on the stack does not work in systems that have separate instruction and data spaces.
We are working with AMD to resolve this, and hope to have it available soon.
