VECTOR SIMD VLIW DATA PATH ARCHITECTURE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18594461 titled 'VECTOR SIMD VLIW DATA PATH ARCHITECTURE

Simplified Explanation:

This patent application describes a Very Long Instruction Word (VLIW) digital signal processor designed for Single Instruction Multiple Data (SIMD) operations on various operand widths and data sizes. It includes a vector compare instruction, a vector conditional instruction, and a predicate unit for processing data in predicate data registers.

• The VLIW digital signal processor is optimized for SIMD operations on different operand widths and data sizes.
• It includes a vector compare instruction that compares two operands and stores compare bits.
• A vector conditional instruction allows conditional operations based on a predicate data register bit.
• The predicate unit performs data processing operations on data in predicate data registers, including unary and binary operations.
• The predicate unit can transfer data between general data registers and predicate data registers.

Key Features and Innovation:

• VLIW digital signal processor for SIMD operations
• Vector compare instruction for operand comparison
• Vector conditional instruction for conditional operations

Original Abstract Submitted

A Very Long Instruction Word (VLIW) digital signal processor particularly adapted for single instruction multiple data (SIMD) operation on various operand widths and data sizes. A vector compare instruction compares first and second operands and stores compare bits. A companion vector conditional instruction performs conditional operations based upon the state of a corresponding predicate data register bit. A predicate unit performs data processing operations on data in at least one predicate data register including unary operations and binary operations. The predicate unit may also transfer data between a general data register file and the predicate data register file.
