Engineering Contradiction Analysis
1Manufacturing precision
If manual optimization of algorithms is performed, then the algorithm can be optimized for hardware implementation, but the process becomes time-consuming and costly, taking engineering months or years
Solution Approach 1:
The system performs self-service by automatically analyzing and optimizing algorithms without human intervention. The automated system parses code, builds computation graphs, identifies redundant operations, and generates optimized hardware implementations, eliminating the need for manual engineering optimization while maintaining high quality results
Solution Approach 2:
The patent replaces the mechanical process of manual algorithm optimization with an automated computational system. Instead of engineers manually analyzing and rewriting code, the system uses automated tools to parse code, build computation graphs, identify redundancies, and generate optimized implementations, substituting human effort with machine-based automation
2Productivity
If more components are added to the chip to improve processing power, then more computations can be performed, but the chip cost increases
Solution Approach 1:
The system extracts and removes redundant computations from the algorithm before hardware implementation. By analyzing the computation graph and identifying operations that do not contribute to the final output, the system eliminates unnecessary components from the hardware design, achieving high productivity with fewer components
Solution Approach 2:
The system changes the representation and organization of computational parameters in the hardware implementation. By optimizing how data flows through the computation graph and reorganizing operations, the system achieves higher throughput without proportionally increasing the number of hardware components, effectively changing the efficiency parameters of the design
3Productivity
If more components are added to the chip to improve processing power, then more computations can be performed, but the power consumption increases making mining unprofitable
Solution Approach 1:
The system extracts and eliminates redundant computational operations that would consume power without contributing to useful work. By removing unnecessary computations from the algorithm and corresponding hardware components, the system reduces power consumption while maintaining the required hash generation speed for profitable mining
Solution Approach 2:
The system applies partial action by computing only what is necessary for the final output. Instead of performing complete computations for all intermediate results, the system identifies and computes only the essential portions needed for the hash function output, reducing overall power consumption while maintaining productivity
4Speed
If the algorithm is optimized to generate hash values faster, then more nonces can be tried in a given period, but the optimization process becomes complex and time-consuming
Solution Approach 1:
The system performs self-service by automatically optimizing the algorithm for speed without requiring manual engineering intervention. The automated process parses the code, builds computation graphs, identifies redundant operations, and generates optimized hardware designs that achieve faster hash generation, eliminating the complexity and time burden of manual optimization
Solution Approach 2:
The system performs preliminary action by optimizing the algorithm structure before hardware implementation. By analyzing and restructuring the computation graph in advance, identifying and removing redundant operations, and pre-optimizing the computational flow, the system prepares the algorithm for high-speed execution without the complexity of post-implementation optimization
Data Source
AI summary
Various embodiments of a method and apparatus are disclosed for creating a new device that implements an algorithm, subject to specified constraints. In some embodiments, an initial algorithm and constraints are received and converted to a new algorithm, upon which the device is based. The method further includes constructing a DAG (Directed Acyclic Graph) from the algorithm received and then reconstructing the DAG to accommodate the constraints. The method and system identify outputs that are of interest, trace the outputs of interest back to the inputs, and ignore inputs and the parts of the DAG that are not needed for generating the outputs of interest. When computing multiple jobs in parallel that each use the same DAG, portions of inputs that are shared by two parallel jobs, and portions of the DAG that compute the shared inputs are determined, and therefore only need to be computed once.
