The POWER1 received two upgrades, one in 1991, with the introduction of the POWER1 + and in 1992, with the introduction of POWER1 ++.

The CPU was the PowerPC, a single-chip version of IBM's POWER1 CPU.

The fused multiply – add operation was introduced as multiply – add fused in the IBM POWER1 ( 1990 ) processor, but has been added to numerous other processors since then:

In 1990, IBM introduced the first out-of-order microprocessor, the POWER1, although out-of-order execution was limited to floating point instructions only.

The POWER1 was introduced in 1990, with the introduction of the IBM RS / 6000 POWERserver servers and POWERstation workstations, which featured the POWER1 clocked at 20, 25 or 30 MHz.

In September 1993, the POWER1 and its variants was succeeded by the POWER2 ( known briefly as the " RIOS2 "), an evolution of the POWER1 microarchitecture.

For computing firsts, the POWER1 would be known for being the first CPU to implement some form of Register renaming and out-of-order execution, a technique that improves the performance of superscalar processors but was previously reserved for mainframes.

The POWER1 was also the origin for the highly successful families of POWER, PowerPC and Power Architecture processors that followed it, measuring in hundreds of different implementations.

Although the POWER1 was a high-end design, it was not capable of multiprocessing, and as such was disadvantaged, as the only way performance could be improved was by clocking the CPU higher, which was difficult to do with such a large multi-chip design.

As the POWER1 was the basis of the POWER2 and P2SC microprocessors, the lack of multiprocessing was passed on to these later POWER processors.

The RSC was a feature-reduced single-chip implementation of the POWER1, a multi-chip central processing unit ( CPU ) which implemented the POWER instruction set architecture ( ISA ).

Like the POWER1, the memory controller and I / O was tightly integrated, with the functional units responsible for the functions: a memory interface unit and sequencer unit ; residing on the same die as the processor.

These upgraded versions were clocked higher than the original POWER1, made possible by improved semiconductor processes.

Although the POWER1 is a 32-bit CPU with a 32-bit physical address, its virtual address is 52 bits long.

The RS / 6000 CPU had 2 configurations, called the " RIOS-1 " and " RIOS. 9 " ( or more commonly the " POWER1 " CPU ).

IBM started the POWER2 processor effort as a successor to the POWER1 two years before the creation of the 1991 Apple / IBM / Motorola alliance in Austin, Texas.

The direct derivatives of the POWER1 are the RISC Single Chip ( RSC ), feature-reduced single-chip variant for entry-level RS / 6000 systems, and the RAD6000, a radiation-hardened variant of the RSC for space applications.

An indirect derivative of the POWER1 is the PowerPC 601, a feature-reduced variant of the RSC intended for consumer applications.

The POWER1 is notable as it represented a number firsts for IBM and computing in general.

The open source GCC compiler removed support for POWER1 ( RIOS ) and POWER2 ( RIOS2 ) in the 4. 5 release.

The total number of transistors featured by the POWER1, assuming that it is a RIOS-1 configuration, is 6. 9 million, with 2. 04 million used for logic and 4. 86 million used for memory.

" This was borrowed into Arabic as al-tub ( الط ّ وب al " the " + tub " brick ") " brick ," which was assimilated into Old Spanish as adobe, still with the meaning " mud brick.

The axioms are referred to as " 4 + 1 " because for nearly two millennia the fifth ( parallel ) postulate (" through a point outside a line there is exactly one parallel ") was suspected of being derivable from the first four.

Unlike other hobbyist computers of its day, which were sold as kits, the Apple I was a fully assembled circuit board containing about 60 + chips.

On the scale he used, the boiling-point of water was marked at + 73 and the melting-point of ice at 51, so that the zero of his scale was equivalent to about − 240 on the Celsius scale.

Disks could be booted from via the standard " Shift + Break " key-combination, if the! BOOT file was present on the disk.

Whereas the AMD K6-III + topped out at 570 MHz due to its short pipeline, even when built on the 180 nm process, the Athlon was capable of clocking much higher.

Like their mobile K6-2 +/ III + predecessors, the CPUs were capable of dynamic clock adjustment for power optimization, and also was the reason for the unlocked multiplier.

The close relationship of alternative algebras and composition algebras was given by Guy Roos in 2008: He shows ( page 162 ) the relation for an algebra A with unit element e and an involutive anti-automorphism such that a + a * and aa * are on the line spanned by e for all a in A.

This album was recorded to a Studer A800 mkIII @ 30ips on BASF / Emtec 900 tape at + 6 / 250 nanowebers per meter.

The name comes from Greek Bosporos ( Βόσπορος ), which the ancient Greeks analysed as bous ' ox ' + poros ' means of passing a river, ford, ferry ', thus meaning ' ox-ford ', which is a reference to Io ( mythology ) from Greek mythology who was transformed into a cow and condemned to wander the earth until she crossed the Bosphorus where she met Prometheus.

Originally Gaussian frequency-shift keying ( GFSK ) modulation was the only modulation scheme available ; subsequently, since the introduction of Bluetooth 2. 0 + EDR, π / 4-DQPSK and 8DPSK modulation may also be used between compatible devices.

To separate berkelium from the unreacted americium, this solution was added to a mixture of ammonium and ammonium sulfate and heated to convert all the dissolved americium into the oxidation state + 6.

Gauss's presumed method was to realize that pairwise addition of terms from opposite ends of the list yielded identical intermediate sums: 1 + 100 = 101, 2 + 99 = 101, 3 + 98 = 101, and so on, for a total sum of 50 × 101 = 5050.

The Australian Government has introduced legislation that requires ISP's to " restrict access to age restricted content ( commercial MA15 + content and R18 + content ) either hosted in Australia or provided from Australia " that was due to commence from 20 January 2008, known as Cleanfeed.

Time Out was followed by several albums with a similar approach, including Time Further Out: Miro Reflections ( 1961 ), using more 5 / 4, 6 / 4, and 9 / 8, plus the first attempt at 7 / 4 ; Countdown: Time in Outer Space ( dedicated to John Glenn ) ( 1962 ), featuring 11 / 4 and more 7 / 4 ; Time Changes ( 1963 ), with much 3 / 4, 10 / 4 ( which was really 5 + 5 ), and 13 / 4 ; and Time In ( 1966 ).

Masters ' Diving events are normally conducted in age-groups of 5 or 10 years, and attract competitors of a wide range of ages and experience ( many, indeed, are newcomers to the sport ); the oldest competitor in a Masters ' Diving Championship was Viola Krahn, who at the age of 101 was the first person in any sport, male or female, anywhere in the world, to compete in an age-group of 100 + years in a nationally organized competition.

It survives in this fixed form from the days of Old English ( having undergone, however, phonetic changes with the rest of the language ), in which it was constructed as "" + " me " ( the dative case of the personal pronoun ) + " thinks " ( i. e., " seems ", < Old English thyncan, " to seem ", a verb closely related to the verb thencan, " to think ", but distinct from it in Old English ; later it merged with " think " and lost this meaning ).

While the new " Coppermine " Pentium III was able to rise up to a final 1. 13 GHz clock speed, K6 III + and 2 + never clocked higher than 570 MHz officially, with overclockers using air cooling achieving around 800 MHz at best.

Ptolemy described Arcturus as subrufa " slightly red ", and it has a B-V color index of + 1. 23, roughly midway between Pollux ( B-V + 1. 00 ) and Aldebaran ( B-V + 1. 54 ).

Being a typical member of the lanthanide series, europium usually assumes the oxidation state + 3, but the oxidation state + 2 is also common: all europium compounds with oxidation state + 2 are slightly reducing.

New kinds of instructions were added as well ; full support for signed integers, base + offset addressing, and self-repeating operations were akin to the Z80 design but were all made slightly more general in the 8086.

However, as a result of conservative fiscal policies and a sound financial system, in 2010 the country credit rating improved slightly to BB + and was kept at that level in 2011.

Taking a year to be of this 6940-day cycle gives a year length of 365 + + days ( the unrounded cycle is much more accurate ), which is slightly more than 12 synodic months.

Tin shows chemical similarity to both neighboring group 14 elements, germanium and lead and has two possible oxidation states, + 2 and the slightly more stable + 4.

In fact, by assuming the Elliott – Halberstam conjecture or a slightly weaker version, they were able to show that there are infinitely many n such that at least two of n, n + 2, n + 6, n + 8, n + 12, n + 18, or n + 20 are prime.

The state school system differs slightly from other London Boroughs, with entry to secondary school starting at the age of 12 + as opposed to 11 +, following on from middle schools.

Their methods put a slightly expanded 200 word lexicostatistical list to much better use than lexicostatistics ' simple cognate counting, following phylogenies of individual words and seeking best fits across the phylogenies of each of the 200 + words across all the languages under study.

+ The version of " Girl About Town " used is a slightly longer version with an additional 4 bars just before the instrumental break ( roughly 1: 45-1: 59 ) than the original vinyl 7 " Version ( 3. 10 ).

If the digits are laid out as a square, it is obvious that each row will sum to 1 + 4 + 2 + 8 + 5 + 7, or 27, and only slightly less obvious that each < u > column </ u > will also do so, and consequently we have a magic square:
