CPU Core
Fig. 2.3. shows the CPU circuit block on the main PCB.
The CPU is an IDT 79R3041-20J which is driven at a clock frequency of 20MHz. This clock
frequency is made by dividing the source clock frequency of 40.0MHz by two. The address
and data bus are both 32bits consisting of AD0 to AD31. The total addressable memory
space is 4Gbytes.
