CPU速度测试结果 Microprocessor Benchmark Results Rabbit Semiconductor 5 Feb. 2000 1. Description of Benchmark Tests A benchmark program was devised to test the floating point performance of the Rabbit 2000 against a number of popular 8-bit microprocessors. In order to ensure that the com- parison was based on practical microprocessor systems the following ground rules were applied. The system must be able to generate standard baud rates. This restricts the clock fre- quencies that can be used. The system must be able to operate using 55 nS access time flash memory to store the code. This avoids system that must use impractical or overly expensive memory to store code. In most cases the actual tests were run using available equipment and in one case a soft- war……
