Stream processor with cryptographic co-processor

Abstract

A microprocessor includes a first processing core, a first cryptographic coprocessor and an integer multiplier unit that is coupled to the first processing core and the first cryptographic co-processor. The first processing core includes an instruction decode unit, an instruction execution unit, a load/store unit. The first cryptographic coprocessor is located on a first die with the first processing core. The first cryptographic co-processor includes a cryptographic control register, a direct memory access engine that is coupled to the load/store unit in the first processing core and a cryptographic memory.

Description

[0001] This application claims priority from U.S. Provisional Patent Application No. 60 / 345,315 filed on Oct. 22, 2001 and entitled "High Performance Web Server," which is incorporated herein by reference in its entirety for all purposes.[0002] 1. Field of the Invention[0003] The present invention relates generally to microprocessors, and more particularly, to microprocessors that include a cryptographic co-processor within the microprocessor die.[0004] 2. Description of the Related Art[0005] Server computers (i.e., servers) process all sorts of data transactions. One common type of data transaction is an encrypted data transaction that typically requires the server to perform at least one of an encryption function and a decryption function. FIG. 1 shows a typical server 102 and client computer 110 that are linked by a network 104, such as the Internet or other network.[0006] FIG. 2 is a high-level block diagram of a typical server 102. As shown, the server 102 includes a processor ...
