Advanced System-on-Chip Design: Interfaces and Memory Mapping
Explore the world of system-on-chip design with a focus on microprocessor interfaces, memory mapping, memory-mapped interfaces, mailboxes, FIFOs, shared memory, and coprocessor interfaces. Learn about unique addresses in the system address space, volatile memory mapping, data transfer mechanisms, and high-throughput coprocessor examples. Dive into reading guide sections for a comprehensive understanding of CoDesign principles.

System-on-Chip Design Microprocessor Interfaces Hao Zheng Comp Sci & Eng U of South Florida 1
Memory-Mapping Interface Each component has an unique address in the system address space. 2
Memory Mapped Interfaces volatileint *MMReg = (int*) 0x8000; int value = *MMReg; *MMReg = 5; 4
FIFOs This FIFO has two slave interfaces. 6
Shared Memory To transfer large chunks of data. 7
Coprocessor Interfaces + high throughput, fixed latency - non-reusable. 8
Coprocessor Interfaces: An Example put rD, FLSx // copy register rD to FSL interface FSLx get rd, FSLx // copy FSL interface FSLx into register rD 9
