Advanced flexible processor computational

AFP Performance Benefits. Comparisons between the performance of the Advanced Flexible Processor and other current super computers have been made on the image processing Change Detection Algorithm. The Advanced Flexible Processor has been determined to be approximately 2,000 times faster than a CDC 6600 on the Change Detection Algorithm, and to provide approximately 100 times the capability of the CDC 7600 computer. The Advanced Flexible Processor is found to perform 20 times faster than its predecessor, the Flexible Processor. 

Computations may be streamed through the Advanced Flexible Processor very efficiently due to dual I/O port characteristics of the internal architecture. Data elements may be independently streamed in and out of the Advanced Flexible Processor through any one or all of the four I/O channels. For example, data may be streamed in through one of the memory I/O channels, computations performed, and then streamed out through one of the other three I/O channels simultaneously. 

Multifunctional Parallelism. The internal architecture of the Advanced Flexible Processor allows multiple computational streams to be constructed and executed in parallel. By way of example, one might imagine the multiply unit requesting operands from one of the memory I/O ports and one of the data memories, while at the same time an adder may be requesting the product computed by the multiplier on a previous machine cycle and another data element from one of the remaining three data memories to serve as input operands for an addition operation. 

AFP Computational Performance. The multiply unit of the Advanced Flexible Processor provides the capability to produce two 16-bit products or one 32-bit product every 20 nanosecond machine cycle. The multiplier also provides the capability to do population and significant counts. The two adders provide the capability of performing four 8-bit adds, two 16-bit adds, or one 32-bit add every 20 nanosecond machine cycle. The shift... 

Special-purpose functional units can replace existing functional units within the Advanced Flexible Processor, allowing processor capabilities to be tailored to the precise application requirements. Modular system construction allows compute power modularity thus, processing systems can be cost-effectively tailored to the users individual requirements.
