CoreConnect

The IBM CoreConnect technology eases the integration and reuse of processor, system, and peripheral cores within standard product and custom system-on-a-chip (SOC) designs. The versatility of CoreConnect allows to assemble custom SOC designs using cores designed to CoreConnect specifications. With time-consuming performance, functional and timing pattern issues resolved, designers can focus on product differentiation - dramatically reducing costs and time-to-market for simple and complex SOC designs.
