Mips branch delay slot exception

MIPS architecture - Wikipedia All MIPS I control flow instructions are followed by a branch delay slot. Unless the branch delay slot is filled by an instruction performing useful work, an nop is substituted. Classic RISC pipeline - Wikipedia

A delay state of Delaying means that the instruction being executed caused a branch to be taken, and the next instruction to execute is in the delay slot. GitHub - Kingcom/armips: An assembler for various ARM and MIPS An assembler for various ARM and MIPS platforms. Builds available at http://buildbot.orphis.net/armips/ - Kingcom/armips US6247124B1 - Branch prediction entry with target line index A computing system contains an apparatus having an instruction memory to store a plurality of lines of a plurality of instructions, and a branch memory to store a plurality of branch prediction entries, each branch prediction entry … US6631392B1 - Method and apparatus for predicting floating A method and apparatus predict whether an overflow or underflow floating-point exception could occur as a result of a data processing system performing a particular floating-point operation.

Description. Restrictions. Exceptions. ADD rd, rs, rt. To add 32-bit integers. If an overflow occurs, then trap.Processor operation is UNPREDICTABLE if a branch, jump, ERET, DERET, or WAIT instruction is placed in the delay slot of a branch or jump. Delay Slot Exception Delay Slots Branch delay slots - gem5 The MIPS R4000, part 9:. The ideal number of branch delay slots in a particular pipeline implementation is dictated by the number of pipeline stages, the presence of register forwarding , what stage of delay slot exception the pipeline the branch conditions are...
