1.4.1.3 Mi-V Soft Processor Configuration

The Mi-V soft processor default Reset Vector Address value is 0x8000_0000. After the device reset, the processor executes the application from TCM, which is mapped to 0x8000_0000. Hence, the Reset Vector Address is set to 0x8000_0000, as shown in the following figure.

TCM is the main memory of the Mi-V processor. It gets initialized with the user application from sNVM.

In the Mi-V processor memory map, the 0x8000_0000 to 0x8000_FFFF address range is defined for TCM memory interface and the 0x6000_0000 to 0x6FFF_FFFF address range is defined for APB interface.

Memory depth: This field is set to 16384 words to accommodate an application of up to 64 KB into TCM. The present application is below 50 KB, so this fits into either sNVM or µPROM. In this design, sNVM is selected as data storage client, as shown in the following figure.
