![]() ![]() Sometimes, counter-intuitively, we can improve overall CPU performance (i.e., reduce CPU time) in a way that increases the instruction count, by using instructions in that inner loop that may do "less work" per instruction, but those instructions finishĬPU Time is the amount of time it takes the CPU to complete a particular program. That does the necessary work using fewer instructions - those instructions do "more work" per instruction. Typically the only way to reduce the instruction count is to add instructions such that those inner loops can be re-written in a way Some microprocessor designers have the freedom to add instructions to or remove instructions from the instruction set. Typical benchmark programs have instruction counts in the millions or billions - even though the program itself mayīe very short, those benchmarks have inner loops that are repeated millions of times. The "instruction count" in microprocessor performance measurement is the number of instructions executed during the run of a program. MFLOPS is a million FLOPS, GFLOPS is a billion FLOPS, and TFLOPS is a trillion FLOPS. Which stands for floating point operations per second. A processor with 5 MIPS can perform 5 million instructions every second. It is directly linked to quality & reliability improvement as cycle time can only be reduced where there is consistent achievement of high quality and reliable process uptimes.One of the most common units of measure in modern processors is the "MIPS", which stands for millions of instructions per second. Reducing the cycle time should increase customer satisfaction, plus improve operating efficiency for the bank.Ĭycle Time & Process Performance.Cycle Time of a key measure for building an understanding of process performance and for driving process efficiency. Can this be reduced by having the customer complete forms in advance of getting to the desk, or by simplifying processes so that the cycle time per customer is reduced? If on average one bank counter employee can complete the transaction requests of 10 customers per hour, then on average the cycle time of each customer is 6 minutes. If the cycle time can be reduced, then it may allow a higher throughput of customers (if that is the focus of the restaurant).Įxample: Consider a bank, where customers go into the bank to complete financial transactions. On average one meal is served every 3 minutes. Measuring and continually reducing cycle time is critical to continued success.Įxample: Consider a restaurant serving 20 meals per hour. Its one of the best online productivity tools for those often finding themselves traveling, in flights, in online meetings or just calling friends and family abroad. The cycle time here is normally given as 24 minutes to produce a single batch of 1000 units.Ĭycle Time calculation in a Service Process.The service industry covers a broad range of process types, such as meal preparation and provision in restaurants, maintenance and repair of electrical and mechanical equipment, many government bodies, the financial industry etc. World Time Buddy (WTB) is a convenient world clock, a time zone converter, and an online meeting scheduler. The cycle time is normally calculated as per the continuous process previous, however, the batch is considered the unit of measure, so that the cycle time is given as a batch cycle time.Įxample. In a pharmaceutical company, 100 batches of product, of batch size 1000 units are produced in a 40 hours week. ![]() Each batch may consist of 10,000 units of product. Therefore the cycle time is 24 minutes on average.Ĭycle Time calculation for Batch Processing.Consider a pharmaceutical company producing product in batch format. So, a processor with a 3.5GHz clock frequency, completes 3.5 billion clock cycles per second. Clock speed is the amount of pulses from the oscillator that are completed per second. The average throughput rate is 1 unit per 0.4 hours, which is one unit every 24 minutes. A clock cycle is the amount of time between two pulses from an oscillator (a device for generating repetitive electric pulses). Where: Throughput rate = (Units Produced or Tasks completed)/ TimeĬycle Time calculation in a Continuous Process.In the vast majority of instances, there will be numerous products or services being processed at any one time, therefore the cycle time calculation needs to be modified as follows:Ĭycle time = Average time between completion of units.Įxample: Consider a manufacturing facility, which is producing 100 units of product per 40 hour week. The formula for cycle time = 1/Throughput rate. In a manufacturing company, involved in large capital products, the cycle time may similarly be the time from raw material receipt through to the time the item of production finishes final inspection. Cycle time is the time between commencement and completion of a process, therefore, in a customer call centre, the cycle time for a customer phone call may be the time difference between answering the call and call completion.
