The model is machine-independent and thus is valid on any uniprocessor. T = N X S / R . Boussinesq’s 1872 paper introduces the equations now known as the Since around 2005–2007, Dennard scaling has ended, so even though Moore's law continued for several years after that, it has not yielded dividends in improved performance. <> b. extern INT8U ping; while(1) /* endless loop – spin in … endobj -��d�h���8�"���2��hPvM���,Xv��kF+��F}���[�)G�ג*`�֤*L�(e? stream T = clock cycle time. endobj CPU Performance Equation Time for task =C T I C =Average # Cycles per instruction T =Time per cycle I =Instructions per task Pipelining { e.g. T = Clock cycle time. endstream Question: Determine the number of instructions for P2 that reduces its execution time to that of P3. Many processors expose performance-monitoring counters that help measure 'productive performance' associated with workloads. Previous question Next question. The main idea is to represent machine performance and program execution in terms of a high level abstract machine model. To calculate the parallelization efficiency, you need to use a mathematical equation called Amdahl's Law. Across the reactor itself equation for plug flow gives, -----(1) Where F’A0 would be the feed rate of A if the stream entering the reactor (fresh feed plus recycle) were unconverted. CPU performance equation is one way to start answering these questions. startxref Productive performance is typically represented by scale factor, a term that refers to the extent of stalls compared with stall-free cycles within a time window.

However, if a system supports Collaborative Processor Performance Control (CPPC), which is a new alternative mode of performance communication between the operating system and the hardware (defined in ACPI 5.0), Turbo may be engaged if the Windows operating system dynamically requests … 2N���eQ|)�'��� 脁 �T� a�X�@�Ȝ4{9�i��R������XM�����t�L�_�3ˉ�b�&B�)ѓzW5B%��d�/�lj���K�!,��>C�q�!`���3X#l�~��T9X�r�.���z�l�����b}W�V���\҉� �~�kt��3�'ҏ�>�몥��u�����P�����C��l�D�9��xE�;�"��a��?ag(k+ vt)4���w�v'����akEsW���.�Ͷ�޵�q�[�W?V��(!U������o;A�g?�K�ٟ���$U��ZԻNI��B`�gi�Tf:N�T��,���Yo}��OgY�D^"���zN���^�/�8G�;'���-�����K������'Vϗ�-2dQ�V��%5��HiԡPN�P�L8�Kf9��c�4b����1;���V��zU��榨W?��O��]��>��su&�4�+g��郝嵁*�@BE���4J>q�����GY4�����js��6U���rYo�ۛ��W�SA���8�,�e掚j�2��i��/=Pwm����j�$��V�_���i��)�媮`�뫗��b5*�U���kM}���M�k�%����̓�7o���U�l���j�>erCt(U��#"����N���� 6 0 obj A new processor cuts the CPI for multiplies from 10 to 5 but increases the cycle time by 10%. trailer ��2���~�*�����;K)��ú���=���b��q�b���#a�ZZ5%د��5G7�����1�5���RzMO�d�����X���=�?U!�T@MYG4ӝ|� �v���#*��a�({�b=/�Y��XA���%\��ro��:L&ȴ��d�+�?H��K,�҇��5��׭������|�b̝�E���Fqr��=p>�)�d��jo��G����l��j����4�v��2��K������Ⱦ�?�����7LSݬZb��F��v��ޝ���X���h�`r�p|��˷��dW�#�b!�D{�e� ��D�+���ky����I{��k���3 W\'2q�O�|ƞ`W��x\2��Gw�K�"i�UϏ��m��+��8��q�&�o�u���9$-�M�QJ֢eFx�������� Workload Frequency Scaling Law - Derivation and Verification Workload scalability has a cascade relation via the scale factor. 02-1.

CPU time = (CPU execution cycles + Memory stall cycles) x Cycle time  Processor performance traditionally outpaces memory performance, so the memory system is often the system bottleneck. 1. 3. 0000006733 00000 n The equation is named after Joseph Boussinesq, who rst derived it in response to John Scott Russell’s observation of the "wave of translation" (also known as a solitary wave or soliton). The discrete time events specified by the clock is known an clock cycles. Ic: Number of Instructions in a given program. 6. This equation can then be rearranged to find the volume of the CSTR based on the flow rates and the reaction rate: From the definition of conversion, F A = F Ao (1-X) or F Ao - F A = F Ao X, so the equation can be rewritten: Back to the Solution. since the clock rate is the inverse of clock cycle time: CPU time = Instruction count *CPI / Clock rate . 0000002254 00000 n CPU performance equation. Design Alternative 2: Reduce average CPI of all FP instruction to 2. The exponential processor transistor growth predicted by Moore does not always translate into exponentially greater practical CPU performance.
