Introduction
This document presents the specification of the TSC691E RT Integer Unit. It is organized in three main chapters:
● Standard IU (TSC691E) Functions (Chapter 3)
● Fault MECHANISM and Test MECHANISM (Chapter 4)
● Electrical and Mechanical Specification (Chapter 5)
Chapter 3 presents the SPARC RISC USER’S GUIDE from Cypress Semiconductor including some adaptations due to the introduction of fault tolerant MECHANISMs, without losing the full binary compatibility with the entire SPARC V7.0 application software base.
Chapter 4 and Chapter 5 deal with the new added functions introduced in the TSC691E to improve the reliability of space applications. These new functions also do not impact the SPARC V7.0 compatibility.
