Bobcat AMD Bobcat List of instruction timings and macro-operation breakdown Explanation of column headings: Instruction: Instruction name. cc means any condition code. For example, Jcc can be JB, JNE, etc. Operands: i = immediate constant, r = any register, r32 = 32-bit register, etc., mm = 64 bit mmx register, xmm = 128 bit xmm register, m = any memory operand including indirect operands, m64 means 64-bit memory operand, etc. Ops: Latency: Reciprocal throughput: Execution pipe: Number of micro-operations issued from instruction decoder to schedulers. Instructions with more than 2 micro-operations are micro-coded. This is the delay that the instruction generates in a dependency chain. The numbers are minimum values. Cache misses, misalignment, and exceptions may increase the clock counts considerably. Floating point operands are presumed to be normal numbers. Denormal numbers, NAN's, infinity and exceptions increase the delays. The latencies listed do not include memory operands where the operand is listed as register or memory (r/m). The clock frequency varies dynamically, which makes it difficult to measure latencies. The values listed are measured after the execution of millions of similar instructions, assuming that this will make the processor boost the clock frequency to the highest possible value. This is also called issue latency. This value indicates the average number of clock cycles from the execution of an instruction begins to a subsequent independent instruction of the same kind can begin to execute. A value of 1/2 indicates that the execution units can handle 2 instructions per clock cycle in one thread. However, the throughput may be limited by other bottlenecks in the pipeline. Indicates which execution pipe is used for the micro-operations. I0 means integer pipe 0. I0/1 means integer pipe 0 or 1. FP0 means floating point pipe 0 (ADD). FP1 means floating point pipe 1 (MUL). FP0/1 means either one of the two floating point pipes. Two micro-operations can execute simultaneously if they go to different execution pipes.
