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 BitBlasterTM, ByteBlasterMVTM, or MasterBlaster download cables.

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.
