HSP45240

Address Sequencer

July 2004

Features

Des cription

• Block Oriented 24-Bit Sequencer

• Configurable as Two Independent 12-Bit Sequencers

• 24 x 24 Crosspoint Switch

The Intersil HSP45240 is a high speed Address Sequencer

which provides specialized addressing for functions like

FFTs, 1-D and 2-D filtering, matrix operations, and image

manipulation. The sequencer supports block oriented

addressing of large data sets up to 24-bits at clock speeds

up to 50MHz.

• Programmable Delay on 12 Outputs

• Multi-Chip Synchronization Signals

• Standard µP Interface

Specialized addressing requirements are met by using the

onboard 24 x 24 crosspoint switch. This feature allows the map-

ping of the 24 address bits at the output of the address genera-

tor to the 24 address outputs of the chip. As a result, bit reverse

addressing, such as that used in FFTs, is made possible.

• 100pF Drive on Outputs

• DC to 50MHz Clock Rate

A single chip solution to read/write addressing is also made

possible by configuring the HSP45240 as two 12-bit

sequencers. To compensate for system pipeline delay, a

programmable delay is provided on 12 of the address out-

puts.

Applications

• 1-D, 2-D Filtering

• Pan/Zoom Addressing

• FFT Processing

The HSP45240 is manufactured using an advanced CMOS

process, and is a low power fully static design. The configu-

ration of the device is controlled through a standard micro-

processor interface and all inputs/outputs, with the exception

of clock, are TTL compatible.

• Matrix Math Operations
