Enhanced Local Bus Controller
10.1.1
The main component of the eLBC is its memory controller, which provides a seamless interface to many
types of memory devices and peripherals. The memory controller is responsible for controlling four
memory banks shared by a GPCM, an FCM, and up to three UPMs. As such, it supports a minimal glue
logic interface to SRAM, EPROM, NOR Flash EEPROM, NAND Flash EEPROM, burstable RAM,
regular DRAM devices, extended data output DRAM devices, and other peripherals. The external address
latch signal (LALE) allows multiplexing of addresses with data signals to reduce the device pin count.The
eLBC also includes a number of data checking and protection features such as write protection and a bus
monitor to ensure that each bus cycle is terminated within a user-specified period.
10.1.2
The eLBC main features are as follows:
