We all are familiar with different processors in our system. Each processor has different features. Today many processors are used in many mobile devices also.
But there are certain drawbacks for a traditional processor. They are:
- They get very hot
- Consumes more power
- Requires a cooling fan
- It runs slowly and lose application performance
The result of these drawbacks is that the system become bigger, clunker and noisier.
Crusoe is the new processor that has been designed especially for the mobile computing market. Mobile computing has been the buzzword for quite long time. Mobile computing devices like laptops, web slates & notebook PCs are getting common these days. The heart of each computer whether a desktop or mobile pc is the microprocessor.
Several microprocessors are obtainable in the market for desktop PCs from firms like Intel, AMD, Cyrix etc.The mobile computing market has never had a processor specifically designed for it. The microprocessors utilized in mobile PCs are optimized versions of the desktop PC microprocessor.
A recently designed microprocessor with low power consumption will still be rejected by the market if the performance is poor. So any attempt in this regard should have a correct ‘performance-power’ balance to confirm industrial success. A recently designed microprocessor should be absolutely x86 compatible that’s they should run x86 applications similar to typical x86 microprocessors since most of the presently accessible software’s are designed to work on x86 platform.
Crusoe Processor Design
The idea of Crusoe is well understood from the easy sketch of the processor design, referred to as ‘amoeba’. In this idea, the x86-design is an ill-defined amoeba containing features like ASCII arithmetic, segmentation, variable-length instructions etc. The amoeba explained how a conventional microprocessor was, in their design, to be divided into hardware and software.
Thus Crusoe was regarded as a hybrid microprocessor that’s it’s a software part and a hardware part with the software layer encompassing the hardware unit. The aim of software is to act as an emulator to translate x86 binaries into native code at run time. Crusoe could be a 128-bit microprocessor fabricated using the CMOS method. The chip’s design relies on a method known as VLIW to confirm design simplicity and high performance.
Other than having execution hardware for arithmetic, logical, shift, and floating point instructions, as in typical processors, the Crusoe processor has terribly distinctive features from traditional x86 designs. To ease the interpretation method from x86 to the core VLIW instruction set, the hardware generates an equivalent condition codes as typical x86 processors and operates on an equivalent 80-bit floating point numbers.0
