Experimentation of Dual Issue

techguyz

Hi all,

Can somebody specify asm code to experiment the dual issue of instructions and how the processor executes parallely ?

Also i tried like performing LDM instruction followed by LSL instruction.

    I presume you mean dual issue in-order like an A7 rather than being able to issue two instructions at a time out of order.

    I'm fairly sure no dual issue processor will bother trying to do a load or store multiple in parallel with anything else. Too big a job checking for dependencies for too little relative gain.
