In this example, data available after the MEM stage (4th stage) of the first instruction is required as input by the EX stage (3rd stage) of the second instruction. Without a bubble, the EX stage (3rd stage) only has access to the output of the previous EX stage. Thus adding a ...
Branch instructions can be placed in branch delay slots by the judicious operation of the Exception Pointer Counter and the BD bit in the Cause register for exception handling.Frank WorrellEnhanced branch delay slot handling with single exception program counter. Worrell F. . 1998...
Some RISCs like PowerPC and ARM do not have a delay slot, but for example MIPS, SPARC, PA-RISC have it. But there are some variations: MIPS and PA-RISC have an annihilation/nullify/likely bit in the instruction, so the programmer can choose that the instruction in the delay slot only...
The 32-bit instruction set architecture includes “prepare to branch” instructions that allow target addresses for branch instructions to be set up in advance of the branch. The 32-bit prepare to branch and branch instructions are combined to execute a 16-bit branch instruction coupled...
previous executions of a branch. Faster, more expensive computers can then run faster by investing in better branch prediction electronics. In a CPU with hardware branch prediction, branch hints let the compiler's presumably superior branch prediction override the hardware's more simplistic branch ...

bool "Never (force delay slot branches)" help Pass the -mcompact-branches=never flag to the compiler in order to force it to always emit branches with delay slots, and make no use of the compact branch instructions introduced by MIPSr6. This is useful if you suspect there may be an is...
(VLIW) machine executes a control part. Generally, the control part has a small basic block (BB) and simple data flow. In the VLIW machine, an instruction execution schedule is determined by a compiler, which is software outside the processor. Meanwhile, the execution schedule inside the ...
Kconfig files describe build-time configuration options (called symbols in Kconfig-speak), how they’re grouped into menus and sub-menus, and dependencies between them that determine what configurations are valid.Kconfig files appear throughout the directory tree. For example, subsys/power/Kconfig def...
