Complex Multiplier – 144pin CPGA

The complex multiplier adder multiplies two complex (16+16) bit words every 50 ns and can be configured to output the complete complex (32+32) bit result within a single clock cycle. The data format is fractional two’s complement. The complex multiplier basically operates in two modes:

Features:

. Complex Number (16+16) * (16+16) Multiplication
. Full 32 bit- Result
. Clock Rate 20 MHz
. Two’s Complement Fractional Arithmetic
. Complex Conjugation of X or Y
. 4 Cycle Fall Through
. Max. Frequency: 20 MHz

3. Product Code: DSP2000

Digital Signal Processor – 120 pin CPGA

This device is a 16-bit fixed-point digital signal processor. It has three separate computational units: MAC, ALU & SHIFTER. It supports separate external program and data memories. Program memory (PM) can contain both data and code. Data memory (DM) contains only data. This device also supports one instruction Cache, whose size is 16 words x 24 bits. It supports both direct & indirect addressing modes.

4. Product Code: CAM9905

Content Addressable Memory – 120 pin CPGA

This device is an Associative Comparator with two modes of operation: RAM and ASSOCIATE. Each location is accessible in RAM mode and any location can be read or written into. Each word can be set to EMPTY state to indicate that the word doesn’t contain any data or to SKIP state so that the word does not participate in comparison process. In addition, each of the 16-bit data fields of a word can be selectively masked off from participating in the comparison process.

Features:

a) 16 word X 48 – bit addressable memory
b) Maximum frequency 15 MHz.

6. Product Code: PP9903

Pythagoras Processor –84 pin CPGA

A Pythagoras Processor which can be configured to convert Cartesian to Polar co-ordinates. This chip converts 16-bit real X and 16-bit imaginary Y inputs into 16-bit magnitude R and 12-bit phase q outputs. The CORDIC (Coordinate Rotation Digital Computer) algorithm is implemented to perform the co-ordinate conversion.
