TC1797
Introduction
2.2
System Architecture of the TC1797
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.
Additional high-level features of the TC1797 include:
• Efficient memory organization: instruction and data scratch memories, caches
• Serial communication interfaces – flexible synchronous and asynchronous modes
• Peripheral Control Processor – standalone data operations and interrupt servicing
• DMA Controller – DMA operations and interrupt servicing
• General-purpose timers
• High-performance on-chip buses
• On-chip debugging and emulation facilities
• Flexible interconnections to external components
• Flexible power-management
The TC1797 is a high-performance microcontroller with TriCore CPU, program and data
memories, buses, bus arbitration, an interrupt controller, a peripheral control processor
and a DMA controller and several on-chip peripherals. The TC1797 is designed to meet
the needs of the most demanding embedded control systems applications where the
competing issues of price/performance, real-time responsiveness, computational power,
data bandwidth, and power consumption are key design elements.
The TC1797 offers several versatile on-chip peripheral units such as serial controllers,
timer units, and Analog-to-Digital converters. Within the TC1797, all these peripheral
units are connected to the TriCore CPU/system via the Flexible Peripheral Interconnect
(FPI) Bus and the Local Memory Bus (LMB). Several I/O lines on the TC1797 ports are
reserved for these peripheral units to communicate with the external world.
