3D Spatial Audio is a rapidly-emerging consumer electronics segment. GOWIN Semiconductor has developed a different way of creating 3D Spatial Audio. Our solution produces sound waves that users' brains detect at only one ear at a time without a headset, and we use this to produce an immersive home theater surround sound experience from a single loudspeaker array. This greatly simplifies home theater systems, opening an upscale niche into a mass market     Features  Original psychoacoustic technology Unique sound waves for each ear, spatially encoded Effective for many listeners in a large area Wall-to-wall, floor-to-ceiling immersive experience Produces a multi-channel immersive sound experience from a single smart speaker MUCH louder than ANY other multi-channel speaker of similar size     Configuration and Scales   Linear arrays 8 or more speakers 1.75" or greater spacing Array width 14" or greater   3D-Cluster arrays 8 or more speakers  Fits in cylinderic shape  8" diameter and 8" height       More Surround Sound From Less Hardware   Algorithm drives all amplifiers and speakers with all the channels all the time All hardware is producing EACH channel Result: +18dB louder sound per channel (1 speaker @ 1 Watt vs. 8 speakers @ 1 Watt each) Lower cost for greater SPL Multi-channel soundbars can be more compact TVs and gaming monitors with embedded micro-speakers can produce impressive surround sound with clearer, more powerful center-channel speech/dialog intelligibility   Total System Architecture    GOWIN's signal processing has been architected for easy implementation into cost-effective consumer products. Its input is compatible with typical "upstream" modules used in many AV receivers and other popular consumer audio products, and its output is compatible with many popular 2-channel and 4-channel Class-D power amplifier ICs. It is capable of being operated as a co-processor that requires no support from other system resources, which further simplifies its implementation         Chip Architecture   It is 100% digital It operates at a relatively low frequency (24.576MHz clock) The volume controls, BIQUAD (parametric EQ) filters and matrix filters are programmed via I2C It requires minimal peripheral circuitry (clock oscillator, power supplies) It requires very little glue logic and support circuitry  

GOWIN now offers an Image Signal Processor (ISP) pipeline and AE/AWB coprocessor which accepts a raw Bayer input stream generated by image sensor and outputs RGB stream with improved image quality for display or recognition purposes. The ISP takes the pixel data in Bayer format and adjusts it through CFA, CCM, and Gamma correction modules, and AEAWB module based on accumulated data in the statistics and histogram engines to provide a clear image which is balanced in color and brightness.

GOWIN now offers multiple USB interface solutions including a USB v2.0 soft PHY and USB v2.0 Device Controller (SIE).  The USB 2.0 interface solution is supported on all GOWIN FPGAs (with exception to the 1NZ) providing a line rate of 480Mbps in USB High Speed mode.  The USB PHY and Device Controller allows GOWIN FPGA designers to easily integrate USB connectivity to their end products without the need for additional silicon ICs or devices.  GOWIN’s USB solution is useful for virtually every market segment including consumer, automotive, industrial and communications.   GOWIN provides USB solutions for v1.1 'Full Speed' and 'High Speed' v2.0 modes.  USB v1.1 operates with a line rate of 12Mbps, which is suitable for control and configuration type applications.  USB v2.0 operates with a line rate of 480Mbps, which is used for data streaming applications.     GOWIN's USB IP's are available in the latest version of GOWIN EDA's IP core generator, which provides a configuration GUI for the PHY as well as the device controller.  Once the IP is generated with the desired configuration the PHY and device controller can be instantiated in a design to provide one or more USB interfaces.  Please note, external PCB requirements are needed for this IP to work properly.   To evaluate the USB v2.0 Soft PHY and Device Controller IPs, GOWIN provides a USB v2.0 reference design targeting the DK-Start USB 2.0 GW2AR18 development board.  The board provides a USB connector along with appropriate trace matching and circuitry to communicate data over USB at High Speed data rates.  The reference design configures the device controller as a VCP (Virtual COM Port) and initializes with native USB serial device drivers on Microsoft Windows and Linux.  The reference design provides an example of a USB to UART bridge with a loop back on the UART data.  Data is transmitted from a computer’s USB port to UART TX and then looped back from UART RX to USB to return the same data back to the computer.  Using a serial port terminal program, developers can type characters on their computer and have it returned to them in the console window.
