en.Wedoany.com Reported - Loongson Technology recently unveiled the Loongson 3C3000, a low-cost server chip based on mature proprietary technology. Designed for the low-cost server market, this new-generation 16-core general-purpose processor delivers general computing performance on par with the Loongson 3C5000.

The Loongson 3C3000 is based on the LA364E processor core design, packaged in FCBGA1371 (37.5mm×37.5mm), and is pin-compatible with the Loongson 3B6000 processor. It features 16 physical cores and 16 logical cores (threads), with a clock speed ranging from 1.5 to 1.8 GHz.

The processor core adopts a 64-bit architecture, supports Loongson's proprietary instruction set LoongArch, and includes 128-bit vector instructions. It has a three-issue out-of-order execution capability, integrating 2 fixed-point units, 1 vector unit, and 2 memory access units. In terms of cache, each core includes 64 KB of private L1 instruction cache and 64 KB of private L1 data cache, with all cores sharing 16 MB of L2 cache. Its memory controller supports 2×72-bit DDR4-2400 with ECC verification.

For I/O interfaces, the chip provides 2 sets of PCIe x16 interfaces, totaling 32 lanes, which can be split into up to 4 x4 or x8 interfaces. Additionally, one PCIe x16 interface can be configured as LCL (Loongson Coherent Link) to support dual-processor interconnection. Other interfaces include 1 SPI, 1 UART, 3 I2C, 1 AVS, and 16 GPIO interfaces.

In terms of power management, the Loongson 3C3000 supports dynamic clock gating for major modules and dynamic frequency scaling for main clock domains, with a typical power consumption of 40W@1.5GHz. For security, the chip integrates Loongson's self-developed security and trusted module, supporting national cryptographic standard encryption and decryption algorithms.

The Loongson 3C3000 directly provides 32 PCIe lanes and 2 memory channels on the processor, aiming to effectively support I/O and memory access performance. Positioned as a low-cost, high-value server CPU, it is suitable for general computing scenarios such as file servers, database servers, web servers, and business process servers for small and medium-sized enterprises.
