Description
Architecture-specific information for Intel Pentium.
The Pentium (also referred to as P5, its microarchitecture, or i586) is a fifth generation, 32-bit x86 microprocessor that was introduced by Intel on March 22, 1993, as the very first CPU in the Pentium brand. It was instruction set compatible with the 80486 but was a new and very different microarchitecture design from previous iterations. The P5 Pentium was the first superscalar x86 microarchitecture and the world's first superscalar microprocessor to be in mass production—meaning it generally executes at least 2 instructions per clock mainly because of a design-first dual integer pipeline design previously thought impossible to implement on a CISC microarchitecture. Additional features include a faster floating-point unit, wider data bus, separate code and data caches, and many other techniques and features to enhance performance and support security, encryption, and multiprocessing, for workstations and servers when compared to the next best previous industry standard processor implementation before it, the Intel 80486.
Considered the fifth main generation in the 8086 compatible line of processors, its implementation and microarchitecture was called P5. As with all new processors from Intel since the Pentium, some new instructions were added to enhance performance for specific types of workloads.
The Pentium was the first Intel x86 to build in robust hardware support for multiprocessing similar to that of large IBM mainframe computers. Intel worked closely with IBM to define this ability and then Intel designed it into the P5 microarchitecture. This new ability was absent in prior x86 generations and x86 copies from competitors.

Member Function Documentation
◆ registerDictionary()
|
overridevirtual |
Property: Register dictionary.
The register dictionary defines a mapping between register names and register descriptors (RegisterDescriptor), and thus how the registers map into hardware.
Since dictionaries are generally not modified, it is permissible for this function to return the same dictionary every time it's called. The dictionary can be constructed on the first call.
Thread safety: Thread safe.
Implements Rose::BinaryAnalysis::Architecture::Base.
◆ matchesHeader()
|
overridevirtual |
Tests whether this architecture matches a file header.
Returns true if this architecture matches the specified file header, and false otherwise.
The default implementation always returns false.
