In calculating the CTP of an aggregation of CEs the following three steps are required:\n1. Calculate the effective calculating rate R for each CE;\n2. Apply the word length adjustment (L) to the effective calculating rate (R), resulting in a Theoretical Performance (TP) for each CE.;\n3. If there is more than one CE, combine the TPs resulting in a CTP for the aggregation.\nDetails for these steps are given in the following sections.\nNote 1. For aggregations of multiple CEs which have both shared and unshared memory subsystems, the calculation of CTP is completed hierarchically, in two steps: first, aggregate the group of CEs sharing memory, second calculate the CTP of the groups using the calculation method for multiple CEs not sharing memory.\nNote 2. CEs that are limited to input/output and peripheral functions (e.g. disk drive, communication and video display controllers) are not aggregated into the CTP calculation.\nThe following table shows the method of calculating the effective calculating rate (R) for each CE:\nStep 1: The effective calculating rate R\nFor CEs implementing Note: Every CE must be evaluated independently\nEffective calculating rate, R\nXP only\n(Rxp)\n13*(txpadd) if no add is implemented use:\n1(txpmult) If neither add nor multiply is implemented use the fastest available arithmetic operation as follows:\n13*txp See Notes X & Y\nFP only\n(Rfp)\nMax\n1tfpadd,1tfpmult See Notes X & Z\nBoth FP and XP\n(R)\nCalculate both Rxp, Rfp\nFor simple logic processors not implementing any of the specified arithmetic operations.\n13*tlog Where\ntlog is the execute time of the XOR, or for logic hardware not implementing the XOR, the fastest simple logic operation.\nSee Notes X & Z\nFor special logic processors not using any of the specified arithmetic or logic operations.\nR=R'*WL/64 Where\nR' is the number of results per second, WL is the number of bits upon which the logic operation occurs, and 64 is a factor to normalize to a 64 bit operation.\nNote W: For a pipelined CE capable of executing up to one arithmetic or logic operation every clock cycle after the pipeline is full, a pipelined rate can be established. The effective calculating rate (R) for such a CE is the faster of the pipelined rate or non-pipelined execution rate.\nNote X: For CEs which perform multiple operations of a specific type in a single cycle (e.g., two additions per cycle or two identical logic operations per cycle), the execution time t is given by:\nt=cycle timethe number of identical arithmetic operations per machine cycle\nCEs which perform different types of arithmetic or logic operations in a single machine cycle are to be treated as multiple separate CEs performing simultaneously (e.g., a CE performing an addition and a multiplication in one cycle is to be treated as two CEs, the first performing an addition in obne cycle and the second performing a multiplication in one cycle).\nIf a single CE has both scalar function and vector function, use the shorter execution time value.\nNote Y: For the CE that does not implement FP add or FP multiply, but that performs FP divide:\nRfp=1tfpdivide\nIf the CE implements FP reciprocal but not FP add, FP multiply or FP divide, then\nRfp=1tfpreciprocal\nIf none of the specified instructions is implemented, the effective FP rate is 0.\nNote Z: In simple logic operations, a single instruction performs a single logic manipulation of no more than two operands of given lengths. In complex logic operations, a single instruction performs multiple logic manipulations to produce one or more results from two or more operands.\nRates should be calculated for all supported operand lengths considering both pipelined operations (if supported), and non-pipelined operations using the fastest executing instruction for each operand length based on:\n1. Pipelined or register-to-register operations. Exclude extraordinarily short execution times generated for operations on a predetermined operand or operands (for example, multiplication by 0 or 1). If no register-to-register operations are implemented, continue with (2).\n2. The faster of register-to-memory or memory-to-register operations; if these also do not exist, then continue with (3).\n3. Memory-to-memory.\nIn each case above, use the shortest execution time certified by the manufacturer.", "extent": null, "status": null, "version": "current", "annotations": [], "outstanding_effects":
