| 12-Bit 800KSPS Low Power SAR-ADC | By Quotes | None | 25 MHz | 180 nm |  |
|
| The SAR-ADC is a low power ADC that is implemented in Successive Approximation architecture. It can provide 12-bit resolution capability with only 3V supply voltage. It accepts an analog input range from 0 to VCC and digitizes the input at a maximum sampling frequency rate of 800KHz at 5V supply voltage. This ADC also includes MUX design to select 0 of 7 analog inputs. The power dissipation is less than 5mW with 5V power supply. This SAR-ADC is implemented in SMIC 0.18μm generic CMOS technology. | Introduction | |||||
| AES Codec with 8-bit datapath | 20000 Points | 1.300 K Gates | 515 MHz | 180 nm | |
|
| The IP core implements the NIST FIPS-197 Advanced Encryption Standard and can be programmed to either encrypt or decrypt 128-bit blocks of data using a 128-bit, 192-bit or 256-bit key. The IP has been carefully designed to require minimum logic resources rendering it an ideal solution for low power applications. This has been achieved by using an 8-bit data path size which means that 16 clock cycles are required to load/unload the 128-bit plaintext/ciphertext block. The encryptor receives the 128-bit plaintext block in 8-bit input symbols and generates the corresponding 128-bit ciphertext block in 8-bit output symbols using a supplied 128, 192, or 256-bit AES key. The pre-computed key values are read from an internal round key RAM. A key expander module is provided as an optional module to allow automatic generation and loading of the round key RAM. The decryptor implements the reverse function, generating plaintext from supplied ciphertext, using the same AES key as was used for encryption. The implementation is very low on latency, high speed with a simple interface for easy integration in SoC applications. | Introduction | |||||

| In some particular application, few pin count but still need chip to chip communication. This IP use one wire bi-direction (open drain) to communication. Just like UART , it is consist of one TX and one RX. User can define their own payload freedomly. All devices are connecting through open-drain pull high bus.

| Our IP core implements the Reed Solomon encoding algorithm and is parameterized in terms of bits per symbol, maximum codeword length and maximum number of parity symbols. It also supports varying on the fly shortened codes. Therefore any desirable code-rate can be easily achieved rendering the decoder ideal for fully adaptive FEC applications. ntRSE core supports continuous or burst decoding.

| Octal SPI Master/Slave Controller | By Quotes | 4.641 K Gates | 500 MHz | None | |
|
| Designed to work with a wide variety of SPI bus variants, the core supports run-time control of several SPI protocol parameters. For example, the SPI frame width can be 1 to 4 bytes, the most significant bit position in a frame, serial clock phase and polarity are all software- programmable. In master mode the core can control up to 32 slaves. A software controllable clock generator derives the serial clock for master mode, by dividing the frequency of a clock line dedicated for that purpose | Introduction | |||||
| BRAINS | 50000 Points | 5.250 K Gates | 1.2 GHz | 40 nm | |
|
| With improvement of technology node and IC design is geting more complex, the ratio of embedded memory in SoCs have been exceeding 50%. The fault types of memory are getting complex. The Memory BIST (Built-In Self-Test) is generated for efficient controlling IC cost. The traditional BIST method is inserted along with single memory. If there are many memories in SoCs, the area and testing time of SoCs are expanded a lot due to insertion of BIST. Therefore the SoCs' cost will increase rapidly because memory testing time is too long. We devoted in developing SRAM testing solutions for a long time. BRAINS is based on memory testing patents to reduce testing time and increase yield rate. In addition, BRAINS has many unique features to increase SoCs' reliability and stability. | Introduction | |||||
| HEART(High Efficient Accumulative Repairing Technical) | 50000 Points | 5.250 K Gates | 2.2 GHz | 40 nm | |
|
| HEART can efficient repair faulty SRAM after using BRAINS. SoCs can mantain correctness of functions and avoid fatal error of system reault in SRAM's defect through SRAM's repairing technical. HEART is SRAM accumulative repairing technical, and it combines advantages of Soft-repair and Hard-repair. HEART supports internal registers of SoCs and external storages of SoCs to record SRAM's faulty information. Once SoCs have new SRAM's defect after using them for a long time, users can repeated repair SRAM's defect through HEART. In addtion, HEART also support "On-Demad" testing and repairing requirement. It means that users can enable system registers of SoCs or signal of HEART to test and repair SRAM at one when SoCs have fatal error situations. | Introduction | |||||
| NVM test and repair | 60000 Points | 5.250 K Gates | 2.2 GHz | 40 nm | |
|
| HEART (High Efficient Accumulative Repairing Technical) is a built-in self-repair (BISR) mechanism which uses to recover errors detected after memory testing and to improve yield rate. This mechanism is implemented with spare memories and a built-in redundancy analyze (BIRA) logics which is designed to allocate the redundancy. It needs a storable device (eFuse, OTP or registers) to store testing results after analysis. We provides an efficient accumulative repairing solution to combine advantages of soft BISR mechanism and hard BISR mechanism for improving yield rate. | Introduction | |||||
| CAN 2.0 & CAN FD Bus Controller Core | By Quotes | 12.000 K Gates | None | None | |
|
| The CAN protocol uses a multi-master bus configuration for the transfer of frames be- tween nodes of the network and manages error handling with no burden on the host processor. The core enables the user to set up economic and reliable links between vari- ous components. It appears as a memory-mapped I/O device to the host processor, which accesses the CAN core to control the transmission or reception of frames. The CAN core is easy to use and integrate, featuring programmable interrupts, data and baud rates; a configurable number of independently programmable acceptance filters; and a generic processor interface or optionally an AMBA APB, or AHB-Lite interface. It imple- ments a flexible buffering scheme, allowing fine-tuning of the core size to satisfy the requirements of each specific application | Introduction | |||||
| AES Codec with 128-bit datapath | 20000 Points | 22.000 K Gates | 260 MHz | 180 nm | |
|
| The IP core implements the NIST FIPS-197 Advanced Encryption Standard and can be programmed to either encrypt or decrypt 128-bit blocks of data using a 128-bit, 192-bit or 256-bit key. The IP has been carefully designed for high throughput applications with optimal logic resources utilization. The encryptor core accepts a 128-bit plaintext input word, and generates a corresponding 128-bit ciphertext output word using a supplied 128, 192, or 256-bit AES key. The decryptor core provides the reverse function, generating plaintext from supplied ciphertext, using the same AES key as was used for encryption. The hardware roundkey expansion logic has been designed as a discrete building block. This allows either to build a complete stand-alone AES solution, or to save logic resources by leaving the key generation process to the user. Alternatively, the roundkey expansion logic can be shared between multiple encryption/decryption cores for optimal silicon area resources utilization. The implementation is very low on latency, high speed with a simple interface for easy integration in SoC applications. | Introduction | |||||
