Host Controllers (Virtual Component Soft IPs)
FUNCTIONAL DESCRIPTION Semiconductor's Z0122 Z0100 Host Controllers (2-port 4-port respectively) designed manage control data flow between host device, collect status activity statistics. There five major blocks Z0122 Z0100 Host Controllers: Master block handles read writes initiated Host Controller system memory. Slave block interface between OHCI operational registers application. List Processor block multiple state machines implement List Service Flow, List Priority, states, services, Status write Back, retirement etc. OHCI specification. Root acts wrapper around HSIE interfaces with Host Controller's List Processor block, FIFO OHCI Registers. Root Port Configuration block implements part OHCI Registers that specific Root state machine every Down Stream Port control port functional states.
FEARURES Open compliant compliant. Root user configurable (e.g. number Down Stream Ports, Power Switching Options, etc) Support (1.5Mhz) high (12Mhz) speed devices bi-directional tri-state buses level sensitive latches User friendly application interface Hooks legacy device support, with Support (System Management Interrupt) pin. APPLICATION application such printers, digital cameras, external cable modems, game controllers, keyboards,
