Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing datapath architectures are inefficient due to the power-of-two parallelism paradigm, which leads to resource wastage and performance bottlenecks when trying to achieve non-power-of-two datacache section processing, resulting in larger device footprints and suboptimal operation speeds.
Innovation Solution
Implementing a generalized parallelism paradigm that allows the datapath architecture to divide datacache into any positive integer number of sections, using translation functions to address discontinuities in column address mapping, enabling efficient resource utilization and faster operation speeds with a smaller device footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If power-of-two parallelism paradigm is used, then datapath architecture is simplified, but resource wastage occurs and device footprint increases
Solution Approach 1:
The patent changes the fundamental parameter of parallelism from power-of-two constraints to any positive integer division. By allowing datacache to be divided into N sections where N can be any positive integer (not limited to powers of two), the system achieves optimal resource utilization for specific performance requirements while avoiding the resource wastage inherent in power-of-two paradigms when N is not a power of two.
Solution Approach 2:
The patent introduces dynamic flexibility in the parallelism paradigm by enabling the datacache to be divided into any positive integer number of sections based on operational requirements. This dynamic adaptability allows the system to optimize resource allocation for specific workloads rather than being constrained by fixed power-of-two architecture, thereby reducing resource wastage while maintaining architectural manageability.
2Device complexity
If power-of-two parallelism paradigm is used, then datapath architecture is simplified, but operation speed is reduced
Solution Approach 1:
The patent changes the parallelism parameter from fixed power-of-two to flexible positive integer division. This parameter change enables the system to achieve higher operation speeds by dividing datacache into optimal numbers of sections (N) that match specific performance requirements, allowing for better resource utilization and faster data processing without the speed limitations imposed by power-of-two constraints.
Solution Approach 2:
The patent enables dynamic optimization of operation speed by allowing the datacache to be divided into any positive integer number of sections based on workload requirements. This dynamic flexibility permits the system to achieve higher speeds for specific operations by selecting optimal division factors, rather than being constrained by the slower performance characteristics of fixed power-of-two architectures.
3Loss of substance
If non-power-of-two sections are processed, then resource efficiency improves, but discontinuities in column address mapping occur
Solution Approach 1:
The patent introduces translation functions as intermediary mechanisms that map logical addresses to physical addresses in the datacache. These translation functions act as mediators between the logical address space and the physical datacache sections, resolving discontinuities in column address mapping while enabling efficient non-power-of-two section division. The translation layer ensures continuous and reliable address mapping regardless of the number of sections.
Solution Approach 2:
The patent segments the datacache into N sections where N can be any positive integer, and introduces translation functions to manage the address mapping between segments. This segmentation approach, combined with translation functions, allows efficient resource utilization across non-power-of-two sections while maintaining reliable and continuous address mapping through the translation layer.
4Productivity
If larger device footprint is used, then parallelism capability increases, but manufacturing cost increases
Solution Approach 1:
The patent changes the parallelism parameter from power-of-two constraints to flexible positive integer division. This parameter change enables the system to achieve high parallelism capability with smaller device footprints by dividing datacache into optimal numbers of sections (N) that match specific performance requirements, avoiding the need for larger architectures solely to achieve power-of-two parallelism levels.
Solution Approach 2:
The patent introduces dynamic flexibility in parallelism configuration, allowing the datacache to be divided into any positive integer number of sections based on operational needs. This dynamic adaptability enables the system to achieve high parallelism capability with minimized device footprint by selecting optimal division factors for each specific workload, rather than over-provisioning for fixed power-of-two requirements.
