The size and ports of Meles are similar to the Raspberry Pi Model B, but instead of using an ARM-based processor, it uses a 2GHz T-Head TH1520 quad-core processor based on the RISC-V architecture.

Attached are the Meles single-board computer ports as follows:

 1 HDMI 2.0 port

 1 Gigabit port

 4 USB 3.0 host ports

 1 USB 2.0 Type-C port

 1 x 3.5mm headphone port

 1 x 40-pin GPIO port

 1 MIPI-DSI 4-channel display interface, support touch screen

 1 x 4-lane MIPI-CSI camera input

 1 dual-lane MIPI-CSI input port

The single-board computer comes with 8 GB or 16 GB of LPDDR 4x-4266 memory, and features an eMMC slot and microSD card reader for storage, measures 85 x 56 mm, and starts at $99.

According to reports, the chip integrates 4 high-performance RISC-V CPUs, supports IEEE802.11ax and is backward compatible with IEEE802.11 a / b / g / n / ac protocols; adopts 2.4GHz / 5GHz dual-band architecture and supports DBDC dual-band Concurrent, as well as multiple high-speed interfaces and various peripheral interfaces, can provide industry-leading RF and baseband performance.

The company said that at present, this chip is mainly used in consumer electronics fields such as TVs, tablets, PCs, and smart speakers. Its performance has reached the international leading level, and it has reached in-depth cooperation with top brand customers.

Wuqi Microelectronics is a semiconductor chip developer, focusing on communications, semiconductors, electronics and other fields. Its products include Bluetooth, communications, AI, Internet of Things chips, etc. It will successfully mass-produce the first Wi- The Fi 4 chip that has been used in the products of manufacturers such as TP-Link.

The company also pointed out that its high-speed data transmission Wi-Fi 6 AP plan will be taped out next year, and the next-generation Wi-Fi 6E and Wi-Fi 7 and other high-end chip products are in the design and pre-research and reserve stages.

This year, Imagination released its first commercial RISC-V core, the real-time IMG RTXM-2200 CPU.

Imagination offers a comprehensive range of GPUs, AI accelerators and CPU cores to help the market transition to heterogeneous system-on-chips (SoCs). The recently announced Catapult CPU family extends the RISC-V ecosystem and is purpose-built to enable various market applications. All Imagination GPUs are compatible with RISC-V SoCs, giving customers full control over their heterogeneous designs.

With this membership upgrade, Imagination will bring key knowledge and technologies in the field of heterogeneous computing and IP to the community, ultimately providing chip designers with more choices and helping to open up the future of RISC-V.

Imagination is a UK-based company that creates semiconductor and software intellectual property (IP). The company’s graphics processing unit (GPU), central processing unit (CPU), and artificial intelligence (AI) technologies enable superior PPA (power, performance, and area) metrics, fast time-to-market, and lower total cost of ownership (TCO). Products based on Imagination IP are used by billions of people around the world in their mobile phones, cars, homes and workplaces.

RISC-V International is a non-profit organization that manages the open standard RISC-V instruction set architecture (ISA), related specifications and interested party communities. RISC-V members, now more than 3180 in 70 countries, work together to contribute to the development of the RISC-V open specification and convene and manage related technical, industry, domain and alliance groups. RISC-V combines a modular technology approach with an open, free licensing model so anyone, anywhere can benefit from RISC-V contributions and the intellectual property generated. RISC-V enables the community to collectively invest in technology, drive future strategies, create faster, enjoy unprecedented design freedom, and dramatically reduce the cost of innovation.

According to reports, the SiFive P670 and P470 support virtualization, including a separate IOMMU for accelerating virtualized device I/O, and a complete out-of-order vector implementation based on the RISC-V Vector v1.0 specification approved last year, also known as the market. The first chip to support the new RISC-V vector encryption extensions, working together in clusters of up to 16 cores.

Built on a 5nm process, the SiFive P670 can reach up to 3.4GHz and claims to offer higher single-thread performance and 2x the compute density compared to traditional solutions, including a 2x 128-bit Vector ALU, compliant with approved RISC -V Vector v1.0 specification for advanced wearables, networking, robotics, mobile, and more.

The P470 is SiFive’s first efficiency-focused out-of-order, area-optimized, vector processor for wearables, consumer and smart home devices and other applications, also using a 5nm process with a maximum frequency of 3.4GHz. SiFive says the P470 expands on the proven P500 series, is significantly smaller than competing solutions, and is optimized for best-in-class performance efficiency and area density. The P470 can also be used with the P670 processor for applications that need to share computing resources while optimizing power consumption.

It’s unclear when the SiFive P670 and P470 processors will be available, but we can look forward to it.
