| MBP-light: A Processor for Management of Distributed Shared Memory (1998) | |||||||||||||||||
Abstract | |||||||||||||||||
| MBP(Memory Based Processor)-light is a dedicated processor for management of cache coherent distributed shared memory (DSM) in a massively parallel processor called JUMP-1. Unlike traditional complicated controllers to manage DSM, it provides a simple but powerful 16-bit RISC processor as a core. On the other hand, memory controller, bus interface and network packet handler are implemented completely with a hardwired logic to require high-speed operation. Using 0:4¯m CMOS embedded array technology and the TBGA (Tape Ball Grid Array) package, it works at 50MHz clock. Compared with chips used in Sequent's NUMA-Q, it supports almost the same performance with much smaller amount of hardware. 1 Introduction JUMP-1 is a prototype of a massively parallel processor developed by a collaboration of 7 Japanese universities[1]. The major goal of this project is to establish techniques to build an efficient cache coherent Distributed Shared Memory (DSM) on a massively parallel processor. A lot of ... | |||||||||||||||||
