Uncommon Carriers John McPhee. Only the kernel code is explicitly represented. We proposed a loop buffer specialized to improve the performance of software-pipelined loops specifically in the following areas Control-oriented code, which contains more branches, saw a larger improvement.

Patent 7,, March Example of software-pipelined loop with one epilog stage collapsed. In the above schedule, very little parallelism has been exploited because ins1ins2and ins3 must execute in order within the given loop iteration.

Unlike software-pipelined loop collapsing, the MLB reduces code size without requiring instruction speculation. The compiler does not make the final decision whether an instruction will become a bit instruction. The advantage of kernel-only code is that there is no code growth.

However, EPIC architecture is sometimes distinguished from a pure VLIW architecture, since EPIC advocates full instruction predication, rotating register files, and a very long instruction word that can encode non-parallel instruction groups. The instructions executed parameter measures the number of instructions executed.

In contrast, the VLIW method depends on the programs providing all the decisions regarding which instructions to execute simultaneously and how to resolve conflicts. The loop body is demarcated by special instructions.
