For example: lw $3, 100($2) add $ ... The solution for the MIPS architecture was the "Branch Delay Slot": ... Opcodes :: Plasma - most MIPS I(TM) opcodes :: OpenCores Branch Delay Slot. There is one branch delay slot. This means that the instuction after a branch is always executed before the CPU decides to take the branch or not. Assembly Example. Also see opcodes.asm which tests all of ...
Example with MIPS, Pipelining and Branch Delay Slot - Stack Overflow
Pipeline - Download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online. Emulation – Maister's Graphics Adventures A very important part of MIPS is the use of a branch delay slot. It is a very unique design aspect of the architecture, which is considered a design flaw today because it was hard-coded to help a very specific micro-architecture. .:: Phrack Magazine ::. Because the instructions overlap within the pipeline, there are some "anomalies" that have to be considered when writing MIPS machine code: - there is a branch delay slot: the instruction following the branch instruction is still in the … Temporal Slot Filling
• Jumps also have a delay slot… Example: more or into branch delay slot: Some RISCs like PowerPC and ARM do not have a delay slot, but for example MIPS, SPARC, PA-RISC have it. ° Instruction slot after a load is called “load delay slot” ° If that instruction uses the result of the load, then the hardware interlock will stall it for
This ties in with the other delay slot issues such as issue #330 for mips and so should be considered when implementing their fix. I have come across another related issue to the mips branch delay problems. It may be ...

Branch Hazards and Static Branch Prediction Techniques
branch delay slot - UCSD CSE
The MIPS processors execute the jump or branch instruction and the delay slot instruction as an indivisible unit. If an exception occurs as a result of executing the delay slot instruction, the branch or jump instruction is not executed, and the exception appears to have been caused by the jump or branch instruction. This behavior of the MIPS ... assembly - MIPS (PIC32): branch vs. branch likely ... So in the R4000 architecture, MIPS added Branch Likely instructions which still always fetch the instruction after the branch from the instruction cache, but only execute it if the branch is taken (opposite of what one might expect). Compilers can then always fill the branch delay slot on such a branch. A loop like: Delay slot - Wikipedia
