: developed as a single chip

implementation of CPU. Its main application is in computing

ec no o y.

The advanced P include:. severa on s ng e c p,

ii. RAM memory cache,

.

: manufactured with memory and some

digital and analog peripherals integrated with a processor core

on single chip.

Over various architectures of MCUs, there is trade offbetween

Functionality vs SWAP & Cost

embedded system.

Effective high speed operation

Reconfiguration capability

Embedded DSP Cores

FPGAs in Embedded Platform are

used in either of the two ways:

(e.g.

Microblaze or Picoblaze as Soft Core and

Power PC as Hard Core)

Digita l S ign a l P r ocesso r (DSP )

: designed to have Embedded Multipliers and DSP blocksfor complex mathematical operations.

Main advantage of DSPs over MCU: Single cycle MAC operation

Easily Implementable usinghigh level languages.

Fixed Point or Floating Point

DSPs (along with PWM Gen,

watchdog timers & fast response interrupts) optimized for Controlapplication

way to easily migrate ones designs without ASIC conversion, re-

ualification or other en ineerin effort.

It provides a over Xilinx FPGAs.

Because EasyPath FPGAs do not require the production of newcustom mask sets, EasyPath FPGAs provide much

charges than ASIC devices.
