This paper presents an event-driven adaptive voltage scaling (AVS) system, where a vanguard collaborates with a rearguard to find a minimal supply voltage. While the vanguard is responsible for the slack cycle time estimation, the rearguard allows voltage over-scaling with a variable-latency datapath. Oscar Gustafsson.

Nov 12, 2015 · Ift201 MIPS Data Path Lecture ... 21 videos Play all MIPS Assembly Architecture/Data Path Wang-Zhao-Liu Q M; 8 ... Data Hazard Example With add and sub instruction in MIPS Datapath ... The datapath acts as a coprocessor that accelerates computational-intensive kernel sections thereby increasing the overall performance. We have previously introduced the datapath which is composed of Flexible Computational Components (FCCs). These components can realize any two-level template of primitive operations. Cache replacement algorithms have focused on managing caches that are in the datapath. In datapath caches, every cache miss results in a cache update. Cache updates are expensive because they induce cache insertion and cache eviction overheads which can be detrimental to both cache performance and cache device lifetime. Note: The Jump control signal first appears in Figure 4.24 of Patterson and Hennessey. In the MIPS Single-Cycle Datapath from this web site, the Branch and Jump control signal are combined into a 2-bit Branch control signal.

The basic datapath (including program counter, register file, arithmetic logic unit, and shifter) was created using full-custom design flow; the datapath's control unit and multiplier-accumulator (MAC) unit were created using synthesis and APR. The on-chip memory and the bond pads were provided to us by the instructor. Datapath alone without Controller. After hooking up the datapath, the first step was to make sure that it worked on its own, independent of the controller. So a test suite was written to verify the datapath's functionality. The .s file can be found in in s2mem/datapath_test.s, tests all instructions except jr and beq It makes it a modular design, where you can think hypothetically, ‘If you have a single die and there is a datapath on the die, you just cut the die into two pieces across the datapath.’ Now you have two chips and you are trying to stitch them back together in the same package and the parallel datapath is joined by this IP.” lui (load upper immediate) to the multicycle datapath described in this chapter.

MIPS-Light Instruction Set Summary. The MIPS-Light ISA is a stripped down version of the MIPS R2000 ISA which is very close to the DLX ISA that is described in the textbook. The main difference between MIPS-Light ISA and DLX ISA concerns the branch instructions. An Example: MIPS From the Harris/Weste book Based on the MIPS-like processor from the Hennessy/Patterson book MIPS Architecture Example: subset of MIPS processor architecture Drawn from Patterson & Hennessy MIPS is a 32-bit architecture with 32 registers Consider 8-bit subset using 8-bit datapath This makes the job of writing this assembly language code easier. For this la instruction, the assembler produces (if symbol array is assigned address 0x00aa0bb0) lui $11, 0x00aa # $11 gets value 0x 00aa 0000 ori $11, $11, 0x0bb0 # $11 gets value 0x 00aa 0bb0 The MIPS architecture does this with LOTS of instructions.

NoGap was used to implement an eight-way SIMD datapath of an ASIP called Sleipnir, which was devised by the Division of Computer Engineering at Linköping University. For contrast, the manually crafted HDL implementation of the Sleipnir was taken. The Plasma CPU is based on the MIPS I (TM) instruction set. There are 32, 32-bit general purpose registers. - The value of register R0 is always zero. - R31 is used as the link register to return from a subroutine. - The program counter (pc) specifies the address of the next opcode. - The exception program counter (epc) register remembers the ...
