A comprehensive set of evaluation modules (EVMs) and development system cards will support concurrent engineering. Together, PE, the CodeWarrior tool suite and EVMs create a comprehensive, scalable tools solution for easy, fast and efficient development. HYBRID MCU/DSP 56857 PRODUCT DOCUMENTATION 56857 PERIPHERAL CIRCUIT FEATURES • General Purpose 16-bit Quad Timer* •Two Serial Communication Interfaces (SCI)* • Serial Peripheral Interface (SPI) Port* •Two Enhanced Synchronous Serial Interface (ESSI) modules* • Computer Operating Properly (COP)/Watchdog Timer •JTAG/Enhanced On-Chip Emulation (OnCE) for unobtrusive, real-time debugging • Six independent channels of DMA • 8-bit parallel Host Interface* •Time of Day (TOD) • Four dedicated GPIO • Up to 47 GPIO * Each peripheral I/O can be used alternately as a General Purpose I/O 56857 MEMORY FEATURES • On-chip Memory – 80 KB Program RAM – 48 KB Data RAM –2 KB Boot ROM – Chip Select Logic used as GPIO • Harvard architecture permits up to three simultaneous accesses to program and data memory 56800E CORE FEATURES • Efficient 16-bit hybrid controller engine with dual Harvard architecture • 120 Million Instructions Per Second (MIPS) at 120MHz core frequency • Single-cycle 16 x 16-bit parallel Multiplier-Accumulator (MAC) • Four (4) 36-bit accumulators, including extension bits • 16-bit bidirectional shifter • Parallel instruction set with unique addressing modes • Hardware DO and REP loops • Three internal address buses and one external address bus • Four internal data buses and one external data bus • Instruction set supports both DSP and controller functions • Four hardware interrupt levels • Five software interrupt levels • Controller-style addressing modes and instructions for compact code • Efficient C compiler and local variable support • Software subroutine and interrupt stack with depth limited only by memory •JTAG/Enhanced OnCE debug programming interface The 56800E core is based on a Harvard-style architecture consisting of three execution units operating in parallel, allowing as many as six operations per instruction cycle. The microprocessor-style programming model and optimized instruction set allow straightforward generation of efficient, compact code for both DSP and MCU applications. The instruction set is also highly efficient for C compilers, enabling rapid development of optimized control applications.
