In addition to second sourcing the version of the Sparc RISC made by Cypress Semiconductor Inc and using it in its future high-end business computer systems, Texas Instruments Inc will collaborate with Sun Microsystems Inc on developing the second generation Sparc, using its EPIC-IIB sub-micron fabrication technology: the agreement with Cypress involves the latter second-sourcing the Texas 74ACT8847 maths co-processor chip, which is optimised for use with the Sparc; Texas also says it plans to apply advanced technologies such as artificial intelligence to future commercial Unix systems, particularly for the solution of complex problems in managing operations of a business.
