CS452 - Real-Time Programming

Possibly Useful Notes

Hardware

Inside the grey box is a small circuit board made by Technologic, a TS-7200. The board has a system on chip, the Cirrus EP9302. It contains an ARM 920T CPU, instruction set ARMv4T, two 16550 UARTs, one with hardware handshaking and one without, and a collection of timers. It also has a floating point coprocessor that can be programmed only in assembly language.
