Overview The SEAforth 40C18 is one of the IntellaSys® Scalable Embedded Array multicore processors. It has an array of 40 cores; each of the C18 cores is a complete computer, with its own ROM, RAM, and interprocessor communication. Together they can deliver up to 26 billion operations per second. The SEAforth 40C18 is a perfect embedded computer solution for consumer applications that demand high processing power and low power dissipation. With 40 nodes to work with, designers can dedicate groups of them to specific tasks such as FFT and DFT algorithms. The result is a tightly coupled, extremely versatile user-defined group of dedicated processors assigned to specific tasks. Some can be doing highly compute-intensive audio processing, while others handle wireless interfaces, external memory, and user interface functions. And since each core has its own ROM and RAM, there is less need to go to external memory. Each core runs asynchronously, at the full native speed of the silicon. During interprocessor communication, synchronization happens automatically; the programmer doesn’t have to create synchronization methods. Communication happens between neighbors through dedicated ports. A core waiting for data from a neighbor goes to sleep, dissipating less than one microwatt. Likewise, a core sending data to a neighbor not ready to receive it goes to sleep until that neighbor accepts it. I/O ports on the SEAforth 40C18 are highly configurable because they are controlled by firmware. The 4-wire SPI port, the 2-wire serial ports, and the single-bit GPIO ports can be programmed to perform a large variety of functions. With the available processing power, wireless solutions become possible without the need for separate wireless chips. Ports can be programmed to support I2C, I2S, asynchronous serial, or synchronous serial ports. Serial ports can also be used to connect multiple SEAforth S40C18s. |
