Automated processor generation system and method for designing a configurable processor
First Claim
1. A system for designing a configurable processor, the system comprising:
- hardware generation means for, based on a configuration specification including a predetermined portion and a user-defined portion, generating a description of a hardware implementation of the processor; and
software generation means for, based on the configuration specification, generating software development tools specific to the hardware implementation;
wherein the user-defined portion of the configuration specification includes scheduling information for one or more instructions executed by the processor;
and wherein the hardware generation means includes means for, based on the scheduling information, determining whether and how to generate a description of the logic of at least one pipeline stage and pipeline stalling logic for inclusion in the description of the hardware implementation of the processor.

Abstract
A system for generating processor hardware supports a language for significant extensions to the processor instruction set, where the designer specifies only the semantics of the new instructions and the system generates other logic. The extension language provides for the addition of processor state, including register files, and instructions that operate on that state. The language also provides for new data types to be added to the compiler to represent the state added. It allows separate specification of reference semantics and instruction implementation, and uses this to automate design verification. In addition, the system generates formatted instruction set documentation from the language specification.
