Review Paper on Crusoe Processor
Anuradha G. Deshmukh, Ulahas B. Shinde · 2013
Abstract — Mobile computing has been the buzzword for quite a long time. Mobile computing devices such as laptop, desktop computer etc.are very important in day to day life and they require microprocessor. Microprocessor is the heart of that devices. desktop computer have very different command on processor that’s why they require lots off transistor and because of transistor they consume more power due to more power processor gets heated this type of processor is called power hungry processor. A hot processor require cooling fan and hardware become noisier bulky. this regard must have a proper 'performance-power ' balance to ensure commercial success. Crusoe is the new microprocessor, which has been designed especially for the mobile computing market. In this paper The new technology, that is Crusoe processor is fundamentally software based: the power savings come from replacing large numbers of transistors with software, and operating frequency is increase up to 1GHz to 1.7GHz. software part consist of Code morphing software(CMS),Very long instruction word(VLIW). Keywords—CMS-Code morphing software OS independent software that acts as an interpreter on top of the processor optimizing instructions and making calculated decisions to enhance the processor’s performance, Interpreter- Interpreter module that interprets x86 instructions, Rollback- when a fault is encountered the state of the working register is rolled back to the state held in the shadow register, Translator- Translator module that recompiles the x86 instructions into optimized VLIW instructions, VLIW- Very long instruction word CPU that executes up to four operations in each clock cycle.
