Ops (B)

Ops (B) was an Allied military deception planning department, based in the United Kingdom, during the Second World War. It was set up under Colonel Jervis-Read in April 1943 as a department of Chief of Staff to the Supreme Allied Commander (COSSAC), an operational planning department with a focus on western Europe. That year, Allied high command had decided that the main Allied thrust would be in southern Europe, and Ops (B) was tasked with tying down German forces on the west coast in general, and drawing out the Luftwaffe in particular.

The department's first operation was a three-pronged plan called Operation Cockade, an elaborate ploy to threaten invasions in France and Norway. Cockade was not much of a success. The main portion of the operation, a deceptive thrust against the Boulogne region named Operation Starkey, intended to draw out the German air arm, failed to elicit a response. The plan was undermined by the fact that any Allied push towards France that year was obviously unlikely.

Ops

In ancient Roman religion, Ops or Opis, (Latin: "Plenty") was a fertility deity and earth-goddess of Sabine origin.

Mythology

In Ops' statues and coins, she is figured sitting down, as Chthonian deities normally are, and generally holds a scepter or a corn spike as her main attributes. The husband of Ops was Saturn. In Roman mythology, and in Greek mythology where Ops is identified as Rhea, her husband was Cronus, the bountiful monarch of the Golden Age. Cronus was Rhea's husband and brother. In Latin writings of the time, the singular nominative (Ops) is not used; only the form Opis is attested by classical authors. According to Festus (203:19), "Ops is said to be the wife of Saturn and the daughter of Caelus. By her they designated the earth, because the earth distributes all goods to the human genus" (Opis dicta est coniux Saturni per quam uolerunt terram significare, quia omnes opes humano generi terra tribuit). The Latin word ops means "riches, goods, abundance, gifts, munificence, plenty". The word is also related to opus, which means "work", particularly in the sense of "working the earth, ploughing, sowing". This activity was deemed sacred, and was often attended by religious rituals intended to obtain the good will of chthonic deities such as Ops and Consus. Ops is also related to the Sanskrit word ápnas ("goods, property").

Ops (Greek mythology)

In Greek mythology, the name Ops (Greek: Ὤψ) may refer to:

Micro-operation

In computer central processing units, micro-operations (also known as a micro-ops or μops) are detailed low-level instructions used in some designs to implement complex machine instructions (sometimes termed macro-instructions in this context).

Usually, micro-operations perform basic operations on data stored in one or more registers, including transferring data between registers or between registers and external buses of the central processing unit (CPU), and performing arithmetic or logical operations on registers. In a typical fetch-decode-execute cycle, each step of a macro-instruction is decomposed during its execution so the CPU determines and steps through a series of micro-operations. The execution of micro-operations is performed under control of the CPU's control unit, which decides on their execution while performing various optimizations such as reordering, fusion and caching.

Optimizations

Various forms of μops have long been the basis for traditional microcode routines used to simplify the implementation of a particular CPU design or perhaps just the sequencing of certain multi-step operations or addressing modes. More recently, μops have also been employed in a different way in order to let modern "CISC" processors more easily handle asynchronous parallel and speculative execution: As with traditional microcode, one or more table lookups (or equivalent) is done to locate the appropriate μop-sequence based on the encoding and semantics of the machine instruction (the decoding or translation step), however, instead of having rigid μop-sequences controlling the CPU directly from a microcode-ROM, μops are here dynamically issued, that is, buffered in rather long sequences before being executed.
