FLEX 10KE Embedded Programmable Logic Devices Data Sheet

Similar to the FLEX 10KE architecture, embedded gate arrays are the
fastest-growing segment of the gate array market. As with standard gate
arrays, embedded gate arrays implement general logic in a conventional
“sea-of-gates” architecture. Additionally, embedded gate arrays have
dedicated die areas for implementing large, specialized functions. By
embedding functions in silicon, embedded gate arrays reduce die area
and increase speed when compared to standard gate arrays. While
embedded megafunctions typically cannot be customized, FLEX 10KE
devices are programmable, providing the designer with full control over
embedded megafunctions and general logic, while facilitating iterative
design changes during debugging.
Each FLEX 10KE device contains an embedded array and a logic array.
The embedded array is used to implement a variety of memory functions
or complex logic functions, such as digital signal processing (DSP), wide
data-path manipulation, microcontroller applications, and data-
transformation functions. The logic array performs the same function as
the sea-of-gates in the gate array and is used to implement general logic
such as counters, adders, state machines, and multiplexers. The
combination of embedded and logic arrays provides the high
performance and high density of embedded gate arrays, enabling
designers to implement an entire system on a single device.
FLEX 10KE devices are configured at system power-up with data stored
in an Altera serial configuration device or provided by a system
controller. Altera offers the EPC1, EPC2, and EPC16 configuration
devices, which configure FLEX 10KE devices via a serial data stream.
Configuration data can also be downloaded from system RAM or via the
Altera BitBlaster
After a FLEX 10KE device has been configured, it can be reconfigured
in-circuit by resetting the device and loading new data. Because
reconfiguration requires less than 85 ms, real-time changes can be made
during system operation.
FLEX 10KE devices contain an interface that permits microprocessors to
configure FLEX 10KE devices serially or in-parallel, and synchronously or
asynchronously. The interface also enables microprocessors to treat a
FLEX 10KE device as memory and configure it by writing to a virtual
memory location, making it easy to reconfigure the device.
