instruction-decode time branch prediction mechanismstrace-driven analysis/ C5220 Computer architectureWe present a new design in which two branch prediction mechanisms are used in conjunction. We show that the combination of these mechanisms will reduce branch penalty, while also reducing chip area....
A processor with out-of-order fetch, decode, and issue temporarily ignores the block associated with the miss, and attempts to fetch, decode, and issue the blocks that follow. The addresses of these blocks are generated by the branch predictor. Because the predictor does not depend on the ...
A computer program consists of a collection of instructions encoded in the binary numbering system. The stages of the fetch execution cycle are the sequence of steps followed by the Central Processing Unit (CPU) as it executes instructions and functions.
Each control state of the FSM implements the transfer of information between the registers of the datapath. The execution sequences through three states: an instruction fetch; an instruction decode; and instruction execute. The controller ... MS Sharawi 被引量: 0发表: 2012年 加载更多来源...

The program should run in a fraction of a second. What did you see instead? The program takes 20 seconds. When I run it on my computer and not in the testing VM, it takes 140 seconds, probably because I actually have the certificates that correspond to the trust settings. This causes ...
10.The method of claim 6, further comprising:forwarding decoded instruction information from a decode stage in a processor pipeline to a training stage in the processor pipeline; anddetermining the fetch width based on the decoded instruction information. ...
An RX data processor 242 processes (e.g., demodulates, deinterleaves, and decodes) each recovered uplink data symbol stream in accordance with the rate used for that stream to obtain decoded data. The decoded data for each user terminal may be provided to a data sink 244 for storage and...
First of all, an aggressive fetch and decode engine must be designed, which is far from being trivial due to branches as well as instruction cache bandwidth issues =-=[2, 3]-=-. Second, an aggressive issue engine with a large instruction window is required to be able to feed a large ...
