The vector block consists of several vector cores that perform several parallel calculations.<\/p>\n
In this case, Semidynamics' vector kernel can be adapted to support FP64, FP32, FP16, BF16, INT64, INT32, INT16 or INT8 data types depending on the requirements - the longest implemented length word defines the width of the vector kernel ('ELEN').<\/p>\n
Its vector units can have 4, 8, 16 or 32 cores and the total data path width of the vector units ('DLEN' = ELEN x number of cores) can be from 128 to 2048 bits.<\/p>\n
A cross-vector network is available in the vector block to connect up to 32 vector cores. "The cross-vector core block is used for special instructions in the RISC-V standard that shuffle data between different vector cores, such as vrgather and vslide," according to semidynamics.<\/p>\n
In vector units, the number of bits of each vector register (VLEN) can be adjusted beyond '1x' (VLEN=DLEN) to 2x, 4x or 8x. "When VLEN is greater than DLEN, the vector operation takes multiple cycles to perform," the company said. \u201cFor example, when VLEN=2048 and DLEN=512, each vector arithmetic operation will take 4 cycles. This is a great feature that allows you to withstand high memory latencies and reduce power consumption.\u201d<\/p>\n
\u201cTogether, our technologies take RISC-V to the next level with the fastest big data processing. is currently available that will open up opportunities in high-performance computing applications such as video processing, AI and machine learning,\u201d said Semidynamics CEO and Founder Roger Espasa.<\/p>\n
The vector unit failed, and paired with Semidynamics' faulty Atrevido 64bit RISC-V core. The cores are still under development, and the company can provide custom interfaces and protocols to match customers' intellectual property.<\/p>\n
Founded in 2016, Semidynamics is located in Barcelona, Spain, and offers a customizable RISC-V processor. IP specializing in high-performance cores with vector blocks for machine learning and AI. It is privately owned and a member of the RISC-V Alliance.<\/p>\n
The European RISC-V Summit will be held in Barcelona from June 5 to 9, 2023. Find Semidynamics at stand 6.<\/p>\n
