DESCRIPTION (CONTINUED)
clock frequencies up to 83 MHz and have read access times as fast as 8 ns.
The 256/512/1,024 x 36 dual-port SRAM FIFO buffers data from port A to port
B. FIFO data on Port B can output in 36-bit, 18-bit, or 9-bit formats with a choice
of Big- or Little-Endian configurations.
These devices are synchronous (clocked) FIFOs, meaning each port
employs a synchronous interface. All data transfers through a port are gated
to the LOW-to-HIGH transition of a port clock by enable signals. The clocks for
each port are independent of one another and can be asynchronous or
coincident. The enables for each port are arranged to provide a simple
bidirectional interface between microprocessors and/or buses with synchro-
nous control.
CommunicationbetweeneachportmaybypasstheFIFOviatwomailbox
registers. The mailbox registers' width matches the selected Port B bus width.
Each mailbox register has a flag (
MBF1 and MBF2) to signal when new mail
has been stored.
TwokindsofresetareavailableontheseFIFOs: ResetandPartialReset.
Reset initializes the read and write pointers to the first location of the memory
array and selects serial flag programming, parallel flag programming, or one
of three possible default flag offset settings, 8, 16 or 64.
PartialResetalsosetsthereadandwritepointerstothefirstlocationofthe
memory. Unlike Reset, any settings existing prior to Partial Reset (i.e.,
programmingmethodandpartialflagdefaultoffsets)areretained. PartialReset
