8-bit Microprocessor

Overview

The iniCPU is a software compatible 6809 microprocessor implemented in VHDL using a stuctured and synchronous design methodology.

This flexible 8-bit microprocessor can be used for low to mid range applications and is easily integrated into any ASIC or FPGA technologies. The iniCPU is designed that application specific performance enhancements (e.g., high-speed multiplier) can be integrated too.

Inicore built a simulation and a hardware verification environment. The simulation environment is VHDL based and simulates the synthesizable VHDL code of the iniCPU. This functional VHDL testbench reading Motorola S-Records from a file can be used for performance check, software verification or to get used to the functionality.

A demonstration board is available which shows the functionality of the iniCPU in a hard ware testbed. For this purpose, the microprocessor is implemented into an Actel FPGA.

Benefits

The 'System-on-Silicon' approach with iniCPU 'on board' enables powerful features such as:
Extended Memory
Software download at start-up
Interfaces to serial EEPROM or cheap DRAM
DMA with any target and optimized communication with customized functions like filter algorithms and other cores like UART, CAN, HDLC, SPI.
For special requirement, like fast interrupt response time, we enhance the iniCPU to your requirment.
Demoboard avaliable
Standard tools e.g. debugger, assembler and C compiler are available from third parties
