Title:
命令セット内の命令に応答してプロセスを実行するデータ処理システムおよびその命令処理方法
Document Type and Number:
Japanese Patent JP4398538
Kind Code:
B2
Abstract:
In-code context data used for exception handling is incorporated into a special call instruction which is recognized by the processor. The information is skipped at the time of the function call and read at the time of the stack unwinding. This special call instruction may be implemented to run at no extra cycle costs compared to normal instructions, except for the external execution time dependencies from such machinery as a cache involved in the instruction fetching, since it would never be necessary during normal execution to actually access the information. The information is only accessed during exception handling.
