Overview

The so_ip_8051C256 is a soft core of a 8-bit CPU dedicated for operation with fast (on-chip) and slow (off-chip) memories.

So_ip_8051C256 soft core is 100% binary compatible with the CPU from industry standard 8051 microcontroller. It executes all ASM51 instructions and has the same instruction set as the 8031.

The so_ip_8051C256 serves both software and hardware interrupts.
So_ip_8051C256 has an advanced architecture that enables it to be 4.51 times faster than the CPU from original 8051 microcontroller.

So_ip_8051C256 is delivered with fully automated testbench and a compete set of tests allowing easy package validation at each stage of SoC design flow.
The so_ip_8051C256 is a microcode-free design developed for reuse in FPGA implementations. The design is strictly synchronous with positive-edge clocking, no internal tri-states and a synchronous reset.

Announcing Arm AGI CPU: The silicon foundation for the agentic AI cloud era

For the first time in our more than 35-year history, Arm is delivering its own silicon products – extending the Arm Neoverse platform beyond IP and Arm Compute Subsystems (CSS) to give customers greater choice in how they deploy Arm compute – from building custom silicon to integrating platform-level solutions or deploying Arm-designed processors.

Encarsia: Evaluating CPU Fuzzers via Automatic Bug Injection

Hardware fuzzing has recently gained momentum with many discovered bugs in open-source RISC-V CPU designs. Comparing the effectiveness of different hardware fuzzers, however, remains a challenge: each fuzzer optimizes for a different metric and is demonstrated on different CPU designs.

Pie: Pooling CPU Memory for LLM Inference

Pie maintains low computation latency, high throughput, and high elasticity. Our experimental evaluation demonstrates that Pie achieves optimal swapping policy during cache warmup and effectively balances increased memory capacity with negligible impact on computation. With its extended capacity, Pie outperforms vLLM by up to 1.9X in throughput and 2X in latency. Additionally, Pie can reduce GPU memory usage by up to 1.67X while maintaining the same performance. Compared to FlexGen, an offline profiling-based swapping solution, Pie achieves magnitudes lower latency and 9.4X higher throughput.
