Titolo: incredibile scambiare archittettura risc per OS

E' successo oggi in queste belle e "simpatiche" aziende di BR.
Sì vede lei e' esperto ci sarebbe una posizione ma lei conosce il risc come 
os?
Il risc e' una architettura non e' un sistema operativo.
Arrivederci.
Anche oggi incontrato cialtrone che aveva pure il coraggio di dirmi che il 
contratto a tempo determinato e' illegale, a momenti gli sputavo in un 
occhio!
P.S. a chi puo' interessare mi scriva privatamente così indico azienda

RISC OS, pronounced 'risk oss', is a computer operating system. RISC OS
first appeared in 1987 as the operating system of the Acorn Archimedes
range of computers. For the Archimedes, Acorn Computers Ltd also designed
their own 32-bit RISC microprocessor, the Acorn Risc Machine (ARM),
because no existing processor suited their needs. RISC OS stands for
Reduced Instruction Set Computer Operating System. RISC OS is believed by
many to be the most user-friendly and stable operating system in the
computing world today. Unlike other desktop computer-based operating
systems, most of RISC OS resides in ROM, so corruption of the operating
system as a result of user error or by a computer virus is practically
impossible. Although the RISC OS brand is now owned by Castle Technology
Ltd, RISCOS Ltd are responsible for desktop computer releases. Over the
last 17 years, RISC OS has been extensively developed and can now be found
in state of the art computers from Castle Technology, Advantage Six,
MicroDigital and in PCs running the Virtual Acorn program.

uhmm BRAVO interessante secondo te intendeva   intendeva l'os del 1987 che 
hai trovato con google?
Oppure intendeva questo che e' un OS da lui dichiarata usata dalla IBM?
RISC, or Reduced Instruction Set Computer. is a type of microprocessor 
architecture that utilizes a small, highly-optimized set of instructions, 
rather than a more specialized set of instructions often found in other 
types of architectures.
History
The first RISC projects came from IBM, Stanford, and UC-Berkeley in the late 
70s and early 80s. The IBM 801, Stanford MIPS, and Berkeley RISC 1 and 2 
were all designed with a similar philosophy which has become known as RISC. 
Certain design features have been characteristic of most RISC processors:
  a.. one cycle execution time: RISC processors have a CPI (clock per 
instruction) of one cycle. This is due to the optimization of each 
instruction on the CPU and a technique called ;
  b.. pipelining: a techique that allows for simultaneous execution of 
parts, or stages, of instructions to more efficiently process instructions;
  c.. large number of registers: the RISC design philosophy generally 
incorporates a larger number of registers to prevent in large amounts of 
interactions with memory
This Site
We will first examine MIPS in detail as an example of an early RISC 
architecture to better understand the features and design of RISC 
architectures. We will then study pipelining to see the performance benefits 
of such a technique. Then we will look at the advantages and disadvantages 
of such a RISC-based architecture as compared to CISC architectures. 
Finally, we will discuss some of the recent developments and future 
directions of RISC processor technology in particular, and processor 
technology as a whole in general.

Settore dell'azienda?

Strano pensavo fossero lider...... 

 
Eh si, infatti sò tutti "lider del settore"
Ma di "lider" non ce n'era uno solo una volta ?
Che schifezza...

 range of computers.
Certo, tutti ci immaginiamo schiere di clienti che usano l'Archimedes,
vero ? :)
Anzi, che io sappia c'e' stata UNA sola persona in Italia che abbia mai
usato un Archimedes, quel folle che su MC Microcomputer si intestardiva
a sfornare articoli su articoli che si rileggeva da solo perche' ce 
l'aveva solo lui... ;-)))))))
