PPT-Dynamic Branch Prediction

Static Branch Prediction Code around delayed branch To reorder code around branches need to predict branch statically when compile Simplest scheme is to predict a branch as taken Average misprediction untaken branch frequency 34 SPEC.

HOTEL LEELA, ANDHERI KURLA ROAD, ANDHERI (E CS448. 2. Instruction Level Parallelism (ILP). Pipelining . Limited form of ILP. Overlapping instructions, these instructions can be evaluated in parallel (to some degree). Pipeline CPI = Idea pipeline CPI + Structural Stalls + RAW stalls + WAR stalls + WAW stalls + Control Stalls. Research Interests/Needs. 1. Outline. Operational Prediction Branch research needs. Operational Monitoring Branch research needs. New experimental products at CPC. Background on CPC. Thanks to CICS/ESSIC/UMD for Inviting us . 5. Branch Prediction . (2.3) and . Scoreboarding. (A.7). 2. Why do we want to predict branches?. MIPS based pipeline – 1 instruction issued per cycle, branch hazard of 1 cycle.. Delayed branch. Modern processor and next generation – multiple instructions issued per cycle, more branch hazard cycles will incur.. Consider executing this sequence of instructions in the pipeline:. address instruction. ----------------------------. 36: sub $10, $4, $8. 40: . beq. $1, $3, 72. 44: and $12, $2, $5. Presentation to AMS Board on Enterprise Communications. September 2012. ESPC Overview. Introduction. ESPC is an . interagency collaboration . between DoD (Navy, Air Force), NOAA, DoE, NASA, and NSF for coordination of research to operations for an earth system analysis and extended range prediction capability. . Branch Prediction. Static Branch Prediction. To reorder code around branches, we need to predict branch statically when compiling. Always taken / not taken. Can be compiler directed. Delayed Branch . As we saw last week, dynamic instruction issue allows us to exploit as much parallelism as exists in instruction code. Our stalling situations are limited to finite resources, cache misses and branches.
