The 60 MHz ARM7 core delivers enough cycles for real-time control loops, protocol stacks (USB, TCP/IP offload), and moderate DSP tasks without needing a dedicated co-processor. The 40 KB SRAM supports multiple packet buffers for USB transfers and keeps the stack deep enough for RTOS task contexts. If your application needs more than 40 KB of working memory, you will either need to use external SRAM via the external bus interface (if available on the variant) or step up to a larger SRAM part in the family.
