Resources
Each core on the XS1-G4 has access to:
- 64 KByte of RAM
- 64 I/O pins that can be accessed using 28 ports: 16 ports access 16 single pins, the other 12 ports access nibbles, bytes, and words of pins.
- 32 channel ends; each channel end can be connected to another channel end setting up a uni directional communication path. Two channels can be set up to point to each other creating a bi directional path.
- 10 timers
The total number of data pins on an XS1-G4 is 256, requiring a 512-pin BGA to bring out all pins (including ground, power, and system pins). The 144 pin BGA only brings out 48 pins of two cores, effectively providing two cores for processing only, and two cores for both processing and I/O.

Famous quotes containing the word resources:
“...wasting the energies of the race by neglecting to develop the intelligence of the members to whom its most precious resources must be entrusted, already seems a childish absurdity.”
—Anna Eugenia Morgan (1845–1909)
“Somehow we have been taught to believe that the experiences of girls and women are not important in the study and understanding of human behavior. If we know men, then we know all of humankind. These prevalent cultural attitudes totally deny the uniqueness of the female experience, limiting the development of girls and women and depriving a needy world of the gifts, talents, and resources our daughters have to offer.”
—Jeanne Elium (20th century)
“I always put these pert jackanapeses out of countenance by looking extremely grave when they expect that I should laugh at their pleasantries; and by saying Well, and so?—as if they had not done, and that the sting were still to come. This disconcerts them, as they have no resources in themselves, and have but one set of jokes to live upon.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
