What your describing is just configurable IO pin routing and peripherals with DMA. That has been common for decades and has nothing to do with ARM, nor is it at all related to Cypress's PSoCs.

The PSoC has an internal switch fabric as well. You aren't just muxxing various blocks to certain pins (e.g. Pin 2.1 is either GPIO, SPI CLK, or UART TX), you can wire blocks to each other internally and then send the output or input to a large choice of pins on the outside.
