NATIVE CODE ARRANGEMENT METHOD, SYSTEM, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To improve hit rates in an instruction cache and a TLB (translation lookaside buffer) when a native code running in a main route in a virtual instruction code execution environment. SOLUTION: A branch detection instruction is embedded with a Java intermediate code 100 in a branch detection instruction embedding section 200, and an intermediate code 300 is generated. The intermediate code 300 is executed serially, and in doing so, the branch detection instruction is executed and one is added to a counter in the branch route of a branch frequency management table 301. A preference path detector 400 looks at the content of the branch frequency management table 301, analyzes branch rates and detects a main route by selecting branch routes with a high branch rates. A memory disposing section 500 disposes the native code of the main route to a memory domain for the main route 502 and disposes the native code of the other route to a memory domain for a rare route 503.
