NAND Flash Memory Controller

NAND Flash Memory Controller

ADOPTED

This NAND flash memory controller supports SLC/MLC/TLC. Two different types are available: host CPU type and AMBA (AXI/AHB/APB) type. The number of NAND interface channels can be customized according to the customer's request; hence it's possible to support wide range of read/write speeds. Moreover, a total solution including firmware for such important functions like Bad Block Management, Wear Levelling (Dynamic/Static), Garbage Collection, etc., can also be provided.

Viterbi Decoder (No External RAM, Soft Decision/SOVA Supported)

ADOPTED

This is a high-speed soft decision Viterbi decoder core, which is widely used as the decoder of convolutional code. Architecture without using external RAM is adopted. Working with our depuncture IP, various code rates are available (2/3, 3/4, 4/5, 5/6,6/7, 7/8 etc).

Radix-16 Viterbi Detector(Soft Decision/SOVA Supported)

ADOPTED

This is radix-16 Viterbi detector core being developed for PRML(Partial Response Maximum Likelihood), which is widely used in HDD/ODD read channel signal processing. Based on our original ACS and pass memory algorithm, both small-size and low-latency is achieved at the same time.

Viterbi Decoder, Viterbi Detector with Noise Prediction

ADOPTED

Error reduction can be significantly improved due to Data Dependent Noise Prediction (DDNP), silicon-proven in HDD, where 10x error reduction has been achieved. Noise prediction parameter auto-tracking is involved.

Viterbi Decoder, Viterbi Detector with the compensation of signal distortion

This is Siglead's original signal distortion compensation technology. Silicon-proven in HDD, where 15x error reduction has been achieved.

Reed-Solomon Code, BCH Code

Reed-Solomon Encoder/Decoder

ADOPTED

This is a high-speed Reed-Solomon encoder/decoder core, which is widely used in the error correction of various storage and communication systems. Four kinds of products are selectable to meet different demands.

Reed-Solomon Codec Generator

ADOPTED

This is a tool for auto-generation of Reed-Solomon encoder/decoder, which is widely used in the error correction of various storage and communication systems. Using this tool, RTL for our IP (Si2520) can be generated.
