Solution Overview
Problem
The execution of conditional statements in computing systems is bottlenecked by digital comparators, which require at least 2 clock cycles per operation and cannot perform parallel execution of multilevel conditional tasks, limiting processor efficiency.
Innovation Solution
Transforming conditional statements into arithmetic and/or bitwise operations, allowing their execution solely by the arithmetic and/or bitwise units of the processor without a digital comparator, enabling faster execution and parallel processing.

1Speed
If a digital comparator is used to evaluate Boolean conditions, then conditional statements can be executed, but the execution speed is limited to at least 2 clock cycles per operation
Solution Approach 1:
The patent replaces the digital comparator (mechanical/electronic comparison system) with an arithmetic unit that performs conditional evaluation through arithmetic operations. Instead of using dedicated comparison hardware that takes 2+ clock cycles, the system uses arithmetic operations (subtraction, multiplication, division) that can complete in 1 clock cycle, thereby increasing execution speed.
Solution Approach 2:
The patent changes the operational parameters by transforming Boolean condition evaluation from a dedicated comparison function into arithmetic operations. By representing conditions as arithmetic expressions (e.g., converting 'a > b' into arithmetic comparisons), the system achieves faster execution by leveraging the 1-clock-cycle capability of arithmetic units rather than being constrained by the 2-clock-cycle minimum of comparator operations.
2Productivity
If a digital comparator is used for conditional evaluation, then Boolean conditions can be assessed, but parallel execution of multilevel conditional tasks is not possible
Solution Approach 1:
The patent segments multilevel conditional tasks into independent arithmetic operations that can be executed in parallel. Instead of processing conditions sequentially through a single comparator, the system divides complex conditional logic into multiple arithmetic expressions that can be evaluated simultaneously by multiple arithmetic units, enabling parallel execution and improving productivity.
Solution Approach 2:
The patent makes the arithmetic unit universal by enabling it to perform both arithmetic calculations and conditional evaluations. The same arithmetic unit that handles mathematical operations also evaluates Boolean conditions through arithmetic expressions, allowing a single unit to serve multiple functions and enabling parallel processing of multilevel conditional tasks.
3Productivity
If a digital comparator is used in the processor, then conditional statements can be executed, but the comparator constitutes a bottleneck limiting overall processor efficiency
Solution Approach 1:
The patent extracts the conditional evaluation function from the digital comparator and integrates it into the arithmetic unit. By removing the dependency on separate comparator hardware and embedding conditional logic within arithmetic operations, the system eliminates the bottleneck and improves processor efficiency without adding complexity.
Solution Approach 2:
The patent merges the conditional evaluation function with the arithmetic unit, combining what were previously separate functions (comparison and arithmetic operations) into a single integrated unit. This consolidation eliminates the bottleneck created by separate comparator hardware and improves overall processor efficiency by reducing device complexity.

AI summary
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for execution of a conditional statement by an arithmetic and/or bitwise unit. A computer program that comprises a conditional statement that comprises a Boolean condition is accessed. The Boolean condition is transformed into an arithmetic and/or bitwise expression of the Boolean condition. An arithmetic and/or bitwise expression of the computer program comprises the arithmetic and/or bitwise expression of the Boolean condition in place of the Boolean condition. The arithmetic and/or bitwise expression of the computer program is executed by an arithmetic and/or bitwise operation unit of a processor.
