This document is designed to be read primarily by design engineers and software engineers who need a detailed description of the interactions of the TC1797 functional units, registers, instructions, and exceptions. This TC1797 Data Sheet describes the features of the TC1797 with respect to the TriCore Architecture. Where the TC1797 directly implements TriCore architectural functions, this manual simply refers to those functions as features of the TC1797. In all cases where this manual describes a TC1797 feature without referring to the TriCore Architecture, this means that the TC1797 is a direct implementation of the TriCore Architecture. Where the TC1797 implements a subset of TriCore architectural features, this manual describes the TC1797 implementation, and then describes how it differs from the TriCore Architecture. Such differences between the TC1797 and the TriCore Architecture are documented in the section covering each such subject. The TC1797 combines three powerful technologies within one silicon die, achieving new levels of power, speed, and economy for embedded applications: • Reduced Instruction Set Computing (RISC) processor architecture • Digital Signal Processing (DSP) operations and addressing modes • On-chip memories and peripherals DSP operations and addressing modes provide the computational power necessary to efficiently analyze complex real-world signals. The RISC load/store architecture provides high computational bandwidth with low system cost. On-chip memory and peripherals are designed to support even the most demanding high-bandwidth real-time embedded control-systems tasks.
