CHAPTER 3 CPU FUNCTIONS
3.4 Address Space
3.4.1 CPU address space
The CPU of the V850ES/KF1, V850ES/KG1, and V850ES/KJ1 uses a 32-bit architecture and supports up to 4 GB
of linear address space (data space) during operand addressing (data access). When addressing instruction
addresses, a linear address space (program space) of up to 64 MB is supported. However, both the program and data
spaces include areas whose use is prohibited. For details, refer to Figure 3-2.
Figure 3-1 shows the CPU address space.
