gatedClock 0:8e898e1270d6 25
gatedClock 0:8e898e1270d6 26 python/Tk code for interfacing with the mbed.org system.
gatedClock 0:8e898e1270d6 27 this code provides a UI which is used to communicate over USB
gatedClock 0:8e898e1270d6 28 to the mbed.org processor, and in turn the toy CPU programmed
gatedClock 0:8e898e1270d6 29 into the altera device.
gatedClock 0:8e898e1270d6 30
gatedClock 0:8e898e1270d6 31 this code provides a UI which is used to monitor and write-to the
gatedClock 0:8e898e1270d6 32 toy CPU's registers and its main memory.
gatedClock 0:8e898e1270d6 33
gatedClock 0:8e898e1270d6 34 I/O capability:
gatedClock 0:8e898e1270d6 35
gatedClock 0:8e898e1270d6 36 * R0 write/read.
gatedClock 0:8e898e1270d6 37 * R1 write/read.

gatedClock 0:8e898e1270d6 39 * R3 write/read.
gatedClock 0:8e898e1270d6 40 * PC write/read. (that's 'Program Counter'.)
gatedClock 0:8e898e1270d6 41 * IR write/read. (that's 'Instruction Register'.)
gatedClock 0:8e898e1270d6 42 * MM address. (that's 'Main Memory.')
gatedClock 0:8e898e1270d6 43 * MM content.
gatedClock 0:8e898e1270d6 44
gatedClock 0:8e898e1270d6 45 Button Controls:
gatedClock 0:8e898e1270d6 46
gatedClock 0:8e898e1270d6 47 * USB Connect/Disconnect.
gatedClock 0:8e898e1270d6 48 * Register Read.
gatedClock 0:8e898e1270d6 49 * Register Write.
gatedClock 0:8e898e1270d6 50 * Main Memory Read.
gatedClock 0:8e898e1270d6 51 * Main Memory Write.
gatedClock 0:8e898e1270d6 52 * Main Memory Load-From-File.
gatedClock 0:8e898e1270d6 53 * Main Memory Dump-To-File.
gatedClock 0:8e898e1270d6 54 * Step CPU.
gatedClock 0:8e898e1270d6 55 * Run-Fast, Run-Slow, Stop CPU.
gatedClock 0:8e898e1270d6 56 * Run Test.
