Sampling theory for environmental analysis

able. The benchmarks given in the introductory report2 are for the Whetstone benchmark and the results are given in Table I. Subsequently, they have published comparative data for IEEE single and double precision performance on the ‘LINPACK’ linear algebra algorithms3 and these are presented in Tables II and III, respectively. These boards with software cost under US $3300 and thus produce substantial computational power for much less cost than a standalone workstation, and the PC or AT clone that houses it can be used for all of the standard MS-DOS software. By using a multitasking program like DoubleDOS, the DSI board can be running in a 90 kilobyte partition in the background and the rest of the memory is available for DOS applications like word processing or data entry. Thus, low cost, easily used, high computational power is readily available by using either of these coprocessor boards.
