Then the NEO430 is the perfect -choice for you! - -This processor is based on the Texas Instruments MSP430(TM) ISA and provides 100% -compatibility with the original instruction set. The NEO430 is not an MSP430 -clone – it is more a complete new implementation from the bottom up. The -processor features a very small outline, already implementing standard -features like a timer, a watchdog, UART and SPI serial interfaces, general -purpose IO ports, an internal bootloader and of course internal memory for -program code and data. All of the peripheral modules are optional – so if you -do not need them, you can exclude them from implementation to reduce the size -of the system. Any additional modules, which make a more customized system, -can be connected via a Wishbone-compatible bus interface. By this, you can -built a system, that perfectly fits your needs. - -It is up to you to use the NEO430 as stand-alone, configurable and extensible -microcontroller, or to include it as controller within a more complex SoC -design. - -The high-level software development is based on the free TI msp430-gcc -compiler tool chain. You can either use Windows or Linux/Cygwin as build -environment for your applications – the project comes with build scripts -for both worlds. The example folder of this project features several demo -programs, from which you can start creating your own NEO430 applications. - -This project is intended to work "out of the box". Just synthesize the test -setup from this project, upload it to your FPGA board of choice and start -exploring the capabilities of the NEO430 processor. Application program -generation (and even installation) works by executing a single "make" command. -Jump to the "Let’s Get It Started" chapter, which provides a lot of guides and -tutorials to make your first NEO430 setup run: -https://github.com/stnolting/neo430/blob/master/doc/NEO430.pdf - - -## Processor Features - -
