Embedded Array Block
The EAB is a flexible block of RAM, with registers on the input and output
ports, that is used to implement common gate array megafunctions.
Because it is large and flexible, the EAB is suitable for functions such as
multipliers, vector scalars, and error correction circuits. These functions
can be combined in applications such as digital filters and
microcontrollers.
Logic functions are implemented by programming the EAB with a read-
only pattern during configuration, thereby creating a large LUT. With
LUTs, combinatorial functions are implemented by looking up the results
rather than by computing them. This implementation of combinatorial
functions can be faster than using algorithms implemented in general
logic, a performance advantage that is further enhanced by the fast access
times of EABs. The large capacity of EABs enables designers to implement
complex functions in a single logic level without the routing delays
associated with linked LEs or field-programmable gate array (FPGA)
RAM blocks. For example, a single EAB can implement any function with
8 inputs and 16 outputs. Parameterized functions, such as LPM functions,
can take advantage of the EAB automatically.
The ACEX 1K EAB provides timing and routing advantages over FPGAs.
FPGAs implement on-board RAM as arrays of small, distributed RAM
blocks that must be connected together to make blocks of manageable
size. The RAM blocks are connected by using multiplexers implemented
with more logic blocks. These extra multiplexers cause extra delay, which,
in turn, slows down the RAM blocks. FPGA RAM blocks are also prone to
routing problems because small blocks of RAM are connected, forming
larger blocks. In contrast, ACEX 1K EABs can be used to implement large,
dedicated blocks of RAM that eliminate these timing and routing
concerns.
The ACEX 1K enhanced EAB supports dual-port RAM. The dual-port
structure is ideal for FIFO buffers with one or two clocks. The ACEX 1K
EAB can also support up to 16-bit-wide RAM blocks. The ACEX 1K EAB
can act in dual-port or single-port mode. When in dual-port mode,
separate clocks may be used for EAB read and write sections, allowing the
EAB to be written and read at different rates. It also has separate
synchronous clock enable signals for the EAB read and write sections,
which allow independent control of these sections.
The EAB can also be used for bidirectional, dual-port memory
applications where two ports read or write simultaneously. To implement
this type of dual-port memory, two EABs are used to support two
simultaneous reads or writes.
