	Dhrystone - a reference guide from Electronicstalk
		We see from your search that you're looking for information on the term "Dhrystone", and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
		Start with the news release Microcontroller fits in compact package from Renesas Technology Europe, which we summarised at the time by saying "Renesas' SH7083F Flash microcontroller delivers 104 Dhrystone MIPS out of its 256/512Kbyte embedded MONOS Flash memory and yet takes up only 140mm3".
		A few weeks before, we featured the news release Multicore SoC processor speeds to 700MHz from NEC Electronics (Europe): "A 90nm, 700MHz dual-core implementation of the ARM11 MPCore multicore processor is billed as the highest-performing ARM processor core on the market".

	What is Dhrystone? 1984 by R.P. Wecker Benchmark Performance (Site not responding. Last check: )
		Developed in 1984 by R.P. Wecker, Dhrystone is a benchmark program written in C or Pascal (and now even in Java) that tests a system's integer performance.
		Dhrystones per second is the metric used to measure the number of times the program can run in a second.
		The original Dhrystone benchmark is still widely used to measure CPU performance in industry under various versions or variants.

	NationMaster - Encyclopedia: Dhrystone
		The Dhrystone grew to become representative of general processor (CPU) performance until it was superseeded by the CPU89 benchmark suite from the Standard Performance Evaluation Corporation, today known as the "SPECint" suite.
		Dhrystone was published in Ada, with the C version for Unix developed by Rick Richardson ("version 1.1") greatly contributing to its popularity.
		Another common representation of the Dhrystone benchmark is the DMIP - Dhrystone MIPS - obtained when the Dhrystone score is divided by 1,757 (the number of Dhrystones per second obtained on the VAX 11/780, nominally a 1 MIPS machine).

	Isolation with Flexibility: A Resource Management Framework for Central Servers
		Dhrystone benefits from all of the exchanges, and the degree of its improvement increases as it receives additional CPU tickets.
		While dhrystone does almost no I/O and can thus afford to give up a large number of disk tickets, iohog needs to be scheduled in order to make progress, and thus the benefit of extra disk tickets is gradually offset by the loss of CPU tickets.
		The non-exchanging iohogs are affected less than the non-exchanging dhrystone because each of them loses only a portion of the bandwidth gained by the exchanging iohog.

	Dhrystone Benchmark adapted for MCUs
		The Dhrystone benchmark was devised many, many years ago to measure the performance of a computer/compiler combination with the specific exclusion of floating-point arithmetic.
		The Dhrystone benchmark is so named because of the lack of floats.) The structure of the benchmark is a loop containing the author's notion of a representative mix of C-language computations.
		The standard distribution of the Dhrystone benchmark is written in the Kernighan and Richie dialect of C. The first step is to convert it to ANSI C to eliminate a large number of errors from an ANSI compiler.

	The Dhrystone benchmark, the LPC2106 and GNU GCC
		The number of "Dhrystones per second" is the time spent in the benchmark divided by number of iterations of the benchmark (in my case, the number of iterations was 500,000).
		It is not documented whether this number is measured or theoretical; the Dhrystone benchmark documents the number of assignments, comparisons, jumps and calls that it makes and therefore you could calculate the Dhrystone result with the processor's instruction set (with cycle counts) in hand.
		In the paper "Benchmarking in context: Dhrystone", Richard York puts forward the argument that the Dhrystone benchmark is actually not very appropriate for predicting the performance of embedded system software; I recommended that you read this paper.

		While the Dhrystone benchmark is well known, it is generally not associated with measuring RTOS performance.
		The Dhrystone tasks check this variable at the end of each pass; if it is not -1, they will request the allocation and place the returned pointer in the allocation table.
		The Dhrystone tasks also check this variable; if it is not -1, the pointer stored in the allocation table at the given index is passed to the free function.

	The Dhrystone Benchmarks
		Dhrystone is a general-performance benchmark test originally developed by Reinhold Weicker in 1984.
		Like most benchmark programs, Dhrystone consists of standard code and concentrates on string handling.
		It is heavily influenced by hardware and software design, compiler and linker options, code optimizing, cache memory, wait states, and integer data types.

	Dhrystone
		Developed by Reinhold Weicker in 1984, dhrystone is a benchmark software program that tests a computer's integer performance and is a good test of the computer processor.
		Each dhrystone is a measurement of how many times the program is able to run each second.
		For example, '1234 dhrystones per second' indicates that the program was capable of running 1,234 times in a one second period.

		Only those results which are from DHRYSTONE 1.1 and mailed to me on the standard form (see the announcement in net.arch or net.micro) will be accepted.
		Also, if you want to remain anonymous, don't send the results to Spencer F. Katt, instead fill in the SUBMITTER line thusly: SUBMITTER: requested anonymity The good news is that this new format allows reporting the information in several ways.
		These things aren't all that reliable a measure of performance, anyhow, and anybody who quibbles over say a 10% difference between machines is missing the point.

	Dr. Dobb's \| Speed Trials: Five C's Compared \| July 22, 2001
		(As most DDJ readers are aware, the Dhrystone is a performance benchmark that times execution of an "average" set of instructions and is as much a benchmark of characters and integer performance as Whetstone is of floating-point performance.
		As the Dhrystone was used as the performance test, all the compilers were directed to generate code with the fastest execution time (instead of optimizing for space).
		Dhrystone run time was by far the best of the bunch at 8.8 seconds, or 5681 Dhrystones per second.

	Dhrystone and MIPs performance of ARM processors
		The idea behind this measure is to compare the performance of a machine (in our case, an ARM system) against the performance of a reference machine.
		The benchmark is calculated by measuring the number of Dhrystones per second for the system, and then dividing that figure by the number of Dhrystones per second achieved by the reference machine.
		By comparing how fast a machine gets a given piece of work done against how fast other machines get that piece of work done, the question of the different instruction sets is avoided.

		That's why we have not progressed beyond Dhrystone, the accepted lowest common denominator that any microprocessor can run.
		Unfortunately, Dhrystone tells us very little about what a microprocessor is good at.
		One could argue that Dhrystone scores say more about the marketing efforts behind a chip than about its technical features.

	Dhrystone - LinuxMIPS
		Dhrystone is one of the oldest benchmarks, yet still in common use.
		It has severe problems due to the small size of the code which will execute from caches even on a modest system, simple code structure which has become a finger exercise for compiler writers and an instruction mix that does not approximate today's workloads.

		These benchmark scores are then used in conjunction with the time taken to process a work unit to calculate how much credit your computer will claim for that work unit.
		The Dhrystone Benchmark tests repeated integer operations together with several operating system file handling operations.

		More recently, I reacquainted myself with exactly how awful Dhrystones are, and how it can and will damage your mental health merely to utter their name.
		I am convinced that Dhrystones should be abolished forever from all discussions related to performance or benchmarking.
		In the insightful words of Dr. Reinhold Weicker, the original creator of Dhrystone, "Although the Dhrystone benchmark that I published in 1984 was useful at the time, it cannot claim to be useful for modern workloads and CPUs because it is so short, it fits in on-chip caches, and fails to stress the memory system.

		Nowadays, an integer benchmark called dhrystone is widely used for bench- marking UNIX systems.
		Be warned, however, that dhrystone is entirely CPU bound, and goes blindingly fast on machines with high-speed caches.
		Although this is a good measure for programs that spend most of their time in some inner loop, it is a poor benchmark for I/O bound applica- tions.
